Answer: okay so the measure of angle 1 is 72 degrees. Angle 2 is 108 degrees. Angle 3 is 72 degrees. And angle 4 is 108 degrees.
Step-by-step explanation:
I know this because to find angle 1 we are going to subtract 180 degrees from 108 degrees. A straight line like this is 180 degrees. Angle 2 is going to be exactly 108 and angle 3 is also going to be 72 degrees. Angle 4 is 108 degrees because 180-72 is 108
Let's see this original ewuation:
1) Substitute 4 in for x:
2)Subtract 4 from both sides. This cancels out four.
3)Cancel:
4)Multiply both sides by negative 1:
So we can factor out th 2 in both becuaase of distributeive porperty
ab+ac=a(b+c)
so
2l+2w=2(l+w)
