Question

9 use the diagram to answer the question below.
solve for $x$.
$x = \square$

Explanation:

Step1: Identify vertical angles

The angles $(x+30)^\circ$ and $2x^\circ$ are vertical angles, so they are equal.

Step2: Set up equation

$x + 30 = 2x$

Step3: Solve for $x$

Subtract $x$ from both sides: $30 = 2x - x$

Answer:

$30$
