Answer 1

Answer: 112°

Explanation:

The angles are supplementary so add to 180°

(2x) + (3x + 10) = 180

Combine Like Terms leaves:

5x + 10 = 180

Subtract 10 from each side:

5x = 170

Divide 5 on each side:

x = 34

Plug x into the large angle

3(34) + 10

Solve:

102 + 10 = 112

The large angle is 112°

Hope this helps!
