Question

A, B, C are the three angles of a triangle. If B - A = 45°, B - C = 15° then, find the values of A, B and C respectively.

Answer 1

Answer:

The answer is

A = 35°, B = 80° , C = 65°

Step-by-step explanation:

A, B, C are the three angles of a triangle.

B - A = 45° - - - - - -(1)

B - C = 15° --------(2)

On addition

2B - A - C = 60° - - - - - - - (3)

Now

A+B+ C=180°

From 3

3B = 240°

B = 80°

A = 80°-45° = 35°

C = 80° - 15° = 65°
