Question

The m∠ABC = (10x-5)°and m∠CBD=35°. If the angles are supplementary, find the value of x.

Answer 1

15

Explanation:

Supplementary angles completes each other to 180°

if the teo angles are supplementary here the the sum of 10x - 5 + 35 should be 180°

10x - 5 + 35 = 180

10x + 30 = 180

10x = 150

x = 15
