Question

solve for x.
(15x)°
(5x + 70)°
x =

Explanation:

Step1: Identify angle relationship

Assume $CD\parallel EF$, then $\angle DGH$ and $\angle GHF$ are corresponding - angles and are equal. So $15x = 5x+70$.

Step2: Solve the equation for x

Subtract $5x$ from both sides of the equation: $15x - 5x=5x + 70-5x$.
$10x=70$.
Divide both sides by 10: $x=\frac{70}{10}=7$.

Answer:

$7$
