Question

solve for x.

Explanation:

Step1: Identify angle - relationship

Assume the angles are corresponding or alternate - interior (parallel lines situation). Set up the equation based on the equality of the two given angles: $5x + 70=15x$.

Step2: Solve the equation

Subtract $5x$ from both sides:
$5x+70 - 5x=15x - 5x$.
$70 = 10x$.

Step3: Isolate x

Divide both sides by 10:
$\frac{70}{10}=\frac{10x}{10}$.
$x = 7$.

Answer:

$7$
