Question

In a triangle ABC angle A is 25 degree more than angle B and angle C is 10 degree less than angle B. What are the angles of the triangle?

Answer 1

angle B = 55 degree
angle A = 80 degree
angle C = 45 degree

Answer 2

Acc. to question,

Angle A=B+25
Angle C=B-10

A+B+C=180°(angle sum property)
B+25+B+B-10=180
3B+15=180
3B=180-15
3B=165
B=165/3
∠B=55°

∠A=B+25
     =55+25
∠A=80°

∠C=B-10
     =55-10
∠C=45°
