Question

Find the measure of an angle which is complement of itself. *
1 point
32 degrees
45 degrees
132 degrees
52 degrees

Answer 1

Answer: Let angle be x° and complement of angle also be x°

we know that sum of angle and complement of angle =90°

then,x+x=90

2x=90

x=45

therefore 45°is the correct answer

Answer 2

Given :

• Find the measure of an angle which is complement of itself.

　

To find :

• What is the complement angle.

　

Complementary angle :

• A angle is considered as complementary angle when the sum of two angles is equal to 90°.

　

Calculation :

→ 45° + 45°

→ 90°

　

Or

　

→ x + x = 90°

→ 2x = 90°

→ x = 90/2

→ x = 45°

　

Therefore, 45° is the angle which is complement of itself.
