Answer:
x = 11
Explanation:
the angle vertically opposite (9x + 19)° is congruent to it , then
(9x + 19)° and 62° are same- side interior angles and sum to 180°
sum the 2 angles, equate to 180 and solve for x , that is
9x + 19 + 62 = 180 ( simplify left side )
9x + 81 = 180 ( subtract 81 from both sides )
9x = 99 ( divide both sides by 9 )
x = 11
