Question

look at the diagram. which equation can be used to solve for x? 27x = 145 30x = 145 2x + 25 = 145 5x + 25 = 145

Explanation:

Step1: Identify vertical - angle relationship

Vertical angles are equal. The angle with measure $(2x + 25)^{\circ}$ and the $145^{\circ}$ angle are vertical angles.

Step2: Set up the equation

Since vertical angles are equal, we can set up the equation $2x+25 = 145$.

Answer:

$2x + 25 = 145$
