Question

In triangle ABC , ∠A – ∠B = 33 degree and ∠ B – ∠ C = 180 degree.Find the measure of each angle of the triangle.

Answer 1

given that

A-B=33

i.e.=A=33+B

B-C=18°

We know that A+B+C=180°

33+B+B+B-18=180

3B+15=180

3B=180-15

3B=165

B=165/3

B=55

A=33+55=88°

C=55-18=37°

Answer 2

Answer:

given

A - B = 33

i.e.=A=33+B

B-C=18°

We know ,that A+B+C=180°

33+B+B+B-18-180

3B+15=180

3B-180-15

3B=165

B=165/3

B=55

A=33+55-88°

C=55-18-37°
