Hi there!
There are many ways to find the measure of an exterior angle of a triangle. I'll explain the easiest method to you. As you can see in the image, a line is drawn extending a side of the triangle. In order to find the measure of the exterior angle, we can subtract the measure of the
adjacent interior angle from 180 (a straight angle). Doing this subtraction will give us the measure of the exterior angle.
Hope this helps!! :)
Answer:
You'd have to go step by step to get the actual value of y. Then solve the equations by inputting the value for y, therefore eliminating y from both equations
360/22.5=16
so the answer is 1/16
