Question

Please help!
An angel is 9 more than half of its supplement. Find the measure of the smaller angle
thanks!

Answer 1

The main challenge is writing the problem in math instead of English. Let the angle be x. Then it's supplement is 180-x. Half its supplement is (180-x)/2. The angle is 9 more than it supplement, so:
\[x=\frac{180-x}{2}+9\]
Do you see how to solve the equation now?

Answer 2

yeah, so first multiply to each side?...

Answer 3

Yeah, exactly. Multiply each side by 2.
