Question

How do I find x?

Answer 1

So every half of a circle is 180 degrees. On the half we are working with, we know that 90 of it is being taken up by the middle angle. This leaves the other two angles, the ones that contain x, to get 90. So we would write the equation\[2x+3x-5=90\] Can you take it from there or do you still need help?
