Find the value of x in the diagram above.
120º
100º
60º
150º
Explicació
\(\angle\)N + \(\angle\)P + \(\angle\)M = 180 ( sum of angles in \(\triangle\) NPM)
65º + 55º + \(\angle\)M = 180
\(\angle\)M = 180 - 65 - 55 = 60º
x + \(\angle\)M = 180(opp interior angles of parallel lines are supplementary)
x = 180 - 60 = 120º
