Answer:
x = 12
Step-by-step explanation:
∠ 5 and 65° are corresponding angles and are congruent, thus
∠ 5 = 65°
∠ 5 and (11x - 17) are adjacent angles and are supplementary, thus
65 + 11x - 17 = 180, that is
11x + 48 = 180 ( subtract 48 from both sides )
11x = 132 ( divide both sides by 11 )
x = 12
