Question

Given the following triangle:

В(2x+4)
A(2x-9)
Find the measure of angle A:
Find the measure of angle B:

Answer 1

A=61, B=74

Explanation:

Because all the angles in a triangle add up to 180:

(2x+4) + (2x-9) + x = 180

If you solve that for x, you will get that x=35. Now you just plug in x to the angles A and B.
