Question

In triangle ABC, the measure of angle A is 40° less than the
angle B and angle B is 50° less than angle C. Find the measures of all
angles.​

Answer 1

Answer:

Let angle C be x degree.

Angle B = ( x-50) degree

Angle C = (x-50-40) = (x-90) degree

In a triangle sum of all angles is 180 degree,

x+x-50+x-90=180

3x-140=180

3x=320

x=106.67 degree

C. 106.67

B. 56.67

A. 10.67
