The sum of the measure of the angles of any triangle is 180 degrees.

Question

In triangle ABC, angles A and B have the same measure, while the measure of angle C is 84 degrees larger than each of A and B. What are the measures of the three angles?

A) Definition of variable(s)

b and c) Equation and solution process:

d) Solution in sentence form with units:

Answer 1

A = measure of angle A

A = measure of angle B     (it's equal to A)

A + 84 = measure of C      (it's 84 more than A)

 

A + A + A + 84 = 180

3A = 96

A = 32

B = 32

C = 116
