Question

If an angle is 45° then its complementary angle is

Answer 1

Given ,

• One complementy angle = 45

Let ,

• The other complementry angle be " x "

We know that ,

The two angles " a " and " b " are said to be complementry angle if :

a + b = 90

Thus ,

45 + x = 90

x = 45

$\therefore \underline{ \sf{The \: complementry \: angle \: is \: 45}}$

Answer 2

Given :

• One angle is 45°
• Complementary angle means 90°

To find :

• Other angle

According to the question,

• Let the other angle be x

→ 45° + x = 90°

→ x = 90° - 45°

.°. x = 45°

• Other angle is 45°
