Question

Find the magnitude of the angle which is
(i) equal to its complementary angle,
(ii) half of its complementary angle,
(iii) 10° more than its complementary angle. please answer step by​

Answer 1

Answer:

i) Let the angle be x

x + x = 90°

2x = 90°

x = 90°/2

= 45°

ii) Let the angle be x

x + 2x = 90°

3x = 90°

x = 90°/3

= 30°

iii) Let the angle be x

x + 10° = 90°

x = 90° - 10°

= 80°
