Angle A is the largest angle; its measure is twice the measure of angle B. The measure of angle C is 2 less than half the measure of Angle B. Find the measures of the three angles in degrees.

Answer 1

I'm going to guess that this is a triangle, although you did not say so...

A = 2B

C = (1/2)B - 2

A + B + C = 180

Substitute:

2B + B + (1/2)B - 2 = 180

3.5B = 182

B = 52

A = 104

C = 24
