Question

A triangle can be described by the following angles Angle 1:6x. Angle 2:6x-9. Angle 3:9x. What is the measure of angle three

Answer 1

Angle 1:6x.

Angle 2:6x-9.

Angle 3:9x.

Angle 1 + Angle 2 + Angle 3 = 180

6x + 6x - 9 +9x = 180

21x - 9 = 180

21x = 180 + 9

21x = 189

x = 189/21

x = 9

Angle 3 = 9*9 = 81°
