Question

solve for x.
(5x + 15)°
70°

Explanation:

Step1: Use the property of same - side interior angles

When two parallel lines are cut by a transversal, same - side interior angles are supplementary. So, \((5x + 15)+70=180\).

Step2: Simplify the equation

$$
LATEXBLOCK0
$$

Step3: Solve for \(x\)

Subtract \(85\) from both sides: \(5x=180 - 85\), \(5x = 95\). Then divide both sides by \(5\): \(x=\frac{95}{5}=19\).

Answer:

\(x = 19\)
