Question

. Find the measure of an angle which is (i) 25° more than its complement​

Answer 1

let the angle be X

then its complementary angle will be X + 25°

A/Q

X + X + 25= 90°

2x + 25°= 90°

2x= 90°-25°

2x= 55°

X = 55/2 I.e. 27.5°

X+25°= 52.5°

Answer 2

Answer :

Let the angle be x

then, it's complement be ( 90° - x )

According to question :-

x = ( 90° - x ) + 25°

x = 90° + 25° - x

x + x = 115°

2x = 115°

x = 115°/2

x = 57.5°

hence, the angle = x = 57.5°
