If angle a is equal to the angle be in the supplement of angle b has a measure of 22° then what is angle a equal to

y=44

We see that there are two angles by the name of "y". Because of this, the triangle is isosceles, meaning that both the angles are the same. Now that we know this, we can find the other angle. Let's call it angle 1.

using sum of angles in a triangle:

m<1= 180-88 .  | this is because of supplementary angles

m<1= 92 .         | algebra

y=180-(92+2y) | sum of angles in a triangle

y=44                | algebra

We can also find it using the exterior angle theorem

2y=88

y=44
