good morning for Traders this is your math video for Thursday you have today assigned Pages 43 and 44 in the excerpt and then you also have page 5 required in your class work homework and Page Six awful 57 degree angle using a scale is where your vertex is going to be a nurse scale the 04 the inner scale is over here on this side so I'm going to go ahead and draw the straight side of the angle 0 and think about where I want my vertex I want my birthday open up in this direction I'm going to go ahead and Slide the key over the vertex hey there's my first sign coming out of zero on the interstate and I need it to be 57 degrees I'm going to follow the inner scale 10 20 30 40 50 and it goes into the directions don't forget to add the curve to show where you measure David not give us letters name this angle so we don't have to use letters next one says 126 degrees using the outer scale of the protractor means that you're a zero is on this side so your vertex is going to be on we're going to go ahead and draw the side of the angle first side a text 0 with the sign we're going to 126 on the outer scale 10 20 30 40 50 all the way past 9125 go over one degree enjoy your curves there's your hundred 26 degree angle using the outer scale so see when you use the outer scale it opens in this direction in her scale it opened in this direction 64 degrees using powder scale our scale again means we're going to want to What are vertex over on this side line up the tea with the vertex zero on the outer scale follow it all the way around till you find 60 465 and go back one degree to 64 and then add your car 159 degrees using the other side the first side What are vertex over here we're going to use the interstate at Interstate I-80 with this side and we're looking for 169 so follow the inner scale until you find one 1 degrees and I'd refer all right next page page 44 more drawing angles you still need your protractor this time they've drawn one side of the angle based on one ready for you to telling you how many degrees to make it and you're just going to start the first one angle ABC needs to be 28 degrees and you can see the vertex is here they're going to line up the key with point B 0 your eyes on the interstate has an inner scale to measure angle so we're going to follow the degrees on the interstate we're looking for 28 30 and then go fast drop point and connect angle ABC we need to go ahead and be on our second side angle ABC and Jessica reviews directions to 28 degrees is less than 90° angle what is playing at the vertex is on this side so we're going to use the other scale the outer scale is 550 / Point d mynetzero with the outer scale so that we follow it around to 89 degrees just shy of 90 degrees just short of being a right angle 89° and connect make sure we add the letter e car permits not quite a right angle so we can't do a straight Square corner and it would be less than 90° or an acute angle if you're feeling confident you can pause the video and go ahead and do the next four and then just check your work when you're done 96° here's our her a text to line up the TV with the vertex 96 degrees 100 95 + 1 degrees it's going to be more open than a right angle but not by much a right angle would be 90° and 696 so little bit what are points 2.8 just a little bigger than a right angle between a greater than less than 180 that makes it angle LMN 102 degrees Sears Arbor attack we're going to be using that out and we're going to a hundred and two so go past 102 degrees past a hundred and a hard to see but here need to add a point when I made out of Arrow your curve is angle is greater than 90 that makes it another obtuse angle Seymour angle pqr 74 degrees here's arbortext lineup thank you 74 degrees on the inner scale since our zeros on the interstate over going to follow the inner scale up to 70 I'm going to look for that halfway mark between 7 Antoinette a darker a Torero we need to add our point and then what type of angle 74° that's less than 90 that makes it an acute angle Play One More over here angle XYZ 35 degrees here's arbortech -50 with -0 zeros on the outer scale we need to 135 to let it go past 9 detox 100 * 1/10 at 1:20 past 1:30 the middle of 130 and 140 Dinero for missing points and then a hundred 35 degrees that's greater than 90 less than 180 that fits into the definition of an odd what is your extra practice for today you do have class work homework page 5 will take a quick look at that this is more decimals and fractions and converting back and forth so remember when we're doing decimals that we have the whole number after the ones comes the 10 and then the hundred fraction has a denominator of 10 we can assume that it goes over one space after the decimal point is it has a denominator of 100 we can assume it was over two places from the decimal point so let's start over one place nominator 3/10 would be 0.3 / 10.4 if it has a hundred as a denominator we can assume it goes over to places from 759 / 0.59 6 over a hundred need to go over to places from the decimal point we only have one digit here so the way we do that if we were to put a 6 first and then a 0 that would be 1600 we wanted to be six so we're going to put the zero first and then the six still goes over to places from the mall so it's 600 send me pictures of fractions where the denominator is not ten or a hundred and four days remember fraction that has either 10 or 100 as a denominator so before we turned into 10 523 * 2A we can just write it as 0.6 we know that we can turn also becomes 5/10 + 0.5 another going to do 5 * 2 to get to 10 so we have to do four times two on the top that's 8/10 or 0.8 play next one if you look at the denominator 25 you're going to realize you cannot turn it into 10 by multiplying but you can turn it into a hundred so thanks 25 times what equals 125 times 4 quarters make a dollar 25 times for The Hundred so what is 12 * 4 that's the basic facts you should know it's 48 and then 48 / 100 is 0.4 is 17 over 50 as you can change it into something over a hundred fifty times too so what's 17 * 2 and multiply it out and you 34 / 100 which is 0.34 13/22 again you're thinking what do I multiply 120 * 5 equals 100 so what's 13 * 5 you can write it to the side and figure it out or you can do it in your head it is 6565 over a hundred would be 0.65 there's a couple here that I want you to try on your own and then a couple of division I miss you one of the division with you and have you do the other one by yourself 3 / 7 how many 7 go into 8 1 1 * 7 is 7 and subtract 8 - 7 is one then you're going to bring down the two so now you're thinking how many 7 go into 12 and 1 * 7 is 712 - 7 is 5 then you bring down at 3 tonight and thinking how 7 going to 53 and that would be 787 * 7 is 49 subtract to get 4th remember we can write 117 remainder 4 or if you're practicing writing fingers as fractions 117 the remainder goes on top and the divisor goes on the bottom of your fraction how to turn into a decimal and one more division to do on
