Question

If (x + 10)°, 35° are complementary angle then x =

Answer 1

Answer:

Complimentary : Sum of the angles = 90°

x + 10 + 35 = 90

=> x = 90 - 45 = 45

Therefore, x = 45°

Answer 2

If (x + 10)°, 35° are complementary angle then x = 45

Given :

(x + 10)°, 35° are complementary angle

To find :

The value of x

Solution :

Step 1 of 2 :

Form the equation to find the value of x

Here it is given that (x + 10)°, 35° are complementary angle

We know that two angles are said to be complementary if sum of the angles is 90°

By the given condition

(x + 10)° + 35° = 90°

Step 2 of 2 :

Find the value of x

(x + 10)° + 35° = 90°

⇒ (x + 10) + 35 = 90

⇒ x + 45 = 90

⇒ x = 90 - 45

⇒ x = 45

Hence the required value of x = 45
