Question

In triangle EFG, m/E = (8x - 16)°, m/F = (x+8)°, and m/G = (2x - 10)°.
What is the value of x?

Answer 1

x = 18

Explanation:

The three angles in a triangle add up to 180° Use this to set up an equation.

8x-16+x+8+2x-10 = 180°

Combine like terms.

11x - 18 = 180

Add 18 to both sides.

11x = 198

Divide by 11

x = 18
