Question

which equation can be used to solve for x in the following diagram? choose 1 answer: a 60+(4x - 20)=90 b 60+(4x - 20)=180 c 60=(4x - 20) d 60 + 90+(4x - 20)=180

Explanation:

Step1: Identify angle - relationship

The two angles \(60^{\circ}\) and \((4x - 20)^{\circ}\) are vertical angles.

Step2: Apply vertical - angle property

Vertical angles are equal. So, \(60=(4x - 20)\).

Answer:

C. \(60=(4x - 20)\)
