Question

Tell whether the angles are adjacent or vertical. Then find the value of x.

The angles are


Question 2
x = ?

Answer 1

x=20

Explanation:

These these angles are adjacent

because they share a vertex and side. They also form a linear pair meaning they add up to 180 degrees...

x+20+7x=180

Combine like terms

8x+20=180

Subtract 20 from both sides

8x=160

Divide both sides by 8

x=20
