Question

write the complement of the following- 28°,30°,67°,(x+5)

Answer 1

Complementary angles sum up to 90°.

I) 28°

Let the complementary angle be x


28° + x = 90
x = 90 - 28
= 62

II) 30°

Let the complementary angle be x


30°+ x = 90
x = 90° - 30°
= 60°

III) 67°

Let the complementary angle be x


67° + x = 90
x = 90 - 67
= 23°

IV) (x +5) °

Let the complementary angle be y

x + 5 + y = 90°
y = 90 - (x +5)
= 90 - x - 5
= 85 - x

Hope this helps....!
