Find the value of x in the diagram above.
The correct answer is: A
Explanation
\(\angle\)N + \(\angle\)P + \(\angle\)M = 180 ( sum of angles in \(\triangle\) NPM)
65ยบ + 55ยบ + \(\angle\)M = 180
\(\angle\)M = 180 - 65 - 55 = 60ยบ
x + \(\angle\)M = 180(opp interior angles of parallel lines are supplementary)
x = 180 - 60 = 120ยบ
