Question

Find the value of x.

Answer 1

The value of x is 30°

Explanation:

The sum of angles of a triangle is equal to 180°

so, x°+66°+84° = 180°

=> x° + 150° = 180°

=> x° = 180°-150°

=> x = 30°

Answer 2

x = 30°

Explanation:

84° + 66° + x = 180°

150° + x = 180°

x = 180° - 150°

x = 30°
