Question

in a triangle abc angle A minus angle b is equal to 15 degree angle B minus angle C is equal to 30 degree find the measure of each angle of the triangle​

Answer 1

Answer:

Step-by-step explanation: sum of interior angle of a triangle

A°+ B° + C° =180° ..... (i)

A- B = 15

A = 15 +B ...... (ii)

B - C =30

C =-30 +B ..... (iii)

Putting (ii) and (iii) in (i)

(15+B) +B +(-30+B) =180°

-15 + 3B =180

3B =195

B=65

Putting B in (ii)

A=80

Put the value of B and A in (i)

C =35

So A +B +C =180

80+65+35 =180
