Vesna [10]3 years ago

Answer:

x=11

Step-by-step explanation:

We know that angles on a straight line equal 180 degrees, so we know that 8x+10+7x+5 = 180.

Simplify

15x+15=180

Solve

<em>Take</em><em> </em><em>away</em><em> </em><em>1</em><em>5</em><em> </em><em>from</em><em> </em><em>both</em><em> </em><em>sides</em>

15x = 165

<em>Divide </em><em>1</em><em>6</em><em>5</em><em> </em><em>by</em><em> </em><em>15</em>

x = 11
