Question

A given angle measures 30° and the measure of its vertical angle is expressed as (5x + 5).

Part A

Write an equation to determine the value of x. Solve for 2.

Enter the correct answers in the boxes.

Answer 1

Equation: 5x+5 = 30

x = 5

Explanation:

Since vertically opposite angles are equal, then;

5x+5 = 30

Subtract 5 from both sides

5x +5-5 = 30-5

5x = 25

x = 25/5

x = 5

The required equation is 5x+5 = 30 (vertically opposite angles are equal)

The value of x is 5
