Question

look at the diagram. which equation can be used to solve for x? 5x + 72 = 180 5x + 38 = 72 5x + 110 = 180 5x = 110 solve for x. x =

Explanation:

Step1: Identify angle - relationship

The angles (72)° and (38)° and (5x)° together form a straight - line, and the sum of angles on a straight - line is 180°.
So, 5x+72 + 38=180.

Step2: Simplify the left - hand side

Combine like terms: 72 + 38 = 110. The equation becomes 5x+110 = 180.

Step3: Solve for x

Subtract 110 from both sides of the equation: 5x=180 - 110. So, 5x = 70. Then divide both sides by 5: x = 14.

Answer:

The equation is 5x + 110 = 180, x = 14
