Question

What is the complementary angle of an angle that measures 30 degrees?

Answer 1

Let the other Complementary Angle be x,

We know that, Sum of Complementary Angles = 90°

therefore,

• 
  `x + 30\degree = 90\degree`

• 
  `x = 90\degree - 30\degree`

• 
  `x = 60\degree`

Answer 2

60

Explanation:

Complementary angles means that the angles add up to 90 degrees

So the complementary of 30 is 60

30+60=90
