Question

in a triangle abc angle C is 9 more than Angle b and Angle b is two less than three times angle find the angle of trainee​

Answer 1

angle B = 3A - 2

angle C = 9 + 3A - 2

now Angle A + Angie B + angle C = 180

A + 3A - 2 + 9 + 3A - 2 = 180

7A +5 = 180

7A = 175

so A = 175/7 = 25

B = 3×25 - 2 = 75-2 = 73

C = 9 + 73 = 82

so angle A = 25 angle B = 73 and angle C= 82
