Question

Find the value of x and give a reason for the relationship between the angles

Answer 1

x = 19

Explanation:

(5x + 2)° + 83° = 180°

✍️Reason: both are linear pair angles. Linear pair angles are supplementary.

Solve for x

5x + 2 + 83 = 180

5x + 85 = 180

Subtract 85 from both sides

5x = 180 - 85

5x = 95

Divide both sides by 5

x = 95/5

x = 19
