x = ?

• 5

• 15

• 12

• 10

Answer explanation

Start by solving for x.

Since all three angles lie on a straight line, the three angles must add up to 180.

We can then write the following equation to solve for x.

6x−10+4x+6+7x+14=180

Combine Like Terms

17x+10=180

17x=180-10

17x=170

x=170/17

x=10
