Question

Please help me asap (geometry)

Answer 1

Answer:

x = 20

Step-by-step explanation:

Angle 2 and Angle 5 are corresponding angles

Corresponding angles are congruent

If angle 2 = 3x - 20 and angle 5 = x + 20

Then 3x - 20 must equal x + 20 ( because corresponding angles are congruent )

Notice that weve just created an equation that we can use to solve for x

We now solve for x using the equation we created

3x - 20 = x + 20

Step 1 add 20 to both sides

3x = x + 40

Step 2 Subtract x from both sides

2x = 40

Step 3 divide both sides by 2

x = 20
