Answer 2

Answer:

Sum of all three angles of triangle = 180

Angle A+ Angle B+ Angle C

1. A +B+C = 180

2. A-B = 15

3. B-C = 30

4. C=B = -30

Add Lhs and Rhs of 2 and 3

A-C = 45

A = 45+C

substitute 3b and 5 in 1

(45 +C) +B+(B-30)=180

45 + (B-30)+2b - 30

3b-15=180

B-5=60

B=65

A= 80

C=35
