The answer is 135°.
The circle has 360°. If it is divided into 8 equal sections, the measure of the angle of each section is 45°:
360° / 8 = 45°
Matt drew an angle that measures the same as the total measure of the 3 sections in the circle. So, the measure of the angle Matt drew is 135°:
3 * 45° = 135°
All you have to do is add 24 to both sides and you will get y. You add 24 so that it will cancel from one side but be added to the other.
The answer is y=17.
Hope this helps!
It is 23!! ...............
