Answer:
Step-by-step explanation:
The angles 7x° and (x + 20)° are supplementary angles.
Supplementary angles add up to 180°.
Therefore we have the equation:
7x + (x + 20) = 180
7x + x + 20 = 180 <em>subtract 20 from both sides</em>
8x = 160 <em>divide both sides by 8</em>
x = 20
A
4(3)+12=24, which is less than 28, so the inequality would be true
i know for a fact angle two is one of the answers.
A complementary angle is where two angles create a 90 degree angle.
