Question

In a triangle abc a is 50 more than b and c is 20 less than b. find the angles

Answer 1

a = 50+b

c = b-20

50+b + b + b - 20 = 180°

3b + 30° = 180°

3b = 150°

b = 50°

Angles are 100° , 50° , 30°

Answer 2

Answer:

The angles are 30°, 50° and 100°

Step-by-step explanation:

A=B+50

C=B-20

A+B+C=180°

B+50+B+B-20=180

3B+30=180

3B=180-30

3B=150

B=50°

A=B+50

A=50+50

A=100°

C=B-20

C=50-20

C=30°
