Question

Whats the value of x

Answer 1

x = 50

Explanation:

These two angles are supplementary angles which means their sum is equal to 180°.

We can write the following equation based on this information:

3x+5+x-25 = 180

• Add like terms

4x - 20 = 180

• Add 20 to both sides

4x = 200

• Divide both sides by 4

x = 50
