Question

Complementary angle (40-x)°

Answer 1

What is the complementary angle to 40 degrees?

In a right angled triangle, the two non-right angles are complementary, because in a triangle the three angles add to 180°, and 90° has already been taken by the right angle. When two angles add to 90°, we say they "Complement" each other.

that is 50

Answer 2

Answer: so firstly what is a complementary angle?

A complementary angle is a sum of two or more angle in which their total sum ans is 90. So let’s take some examples

. What is the complement of <60?

Complement of angle 60.

60+X=90

X=90-60

X=30

…………… so our complement of angle 60 is 30
