Solution

The correct option is D

Interior angles on the same side of transversal are supplementary.
x+ 50 $^{\circ}$ = 180 $^{\circ}$
x = 180 $^{\circ}$ - 50 $^{\circ}$
x = 130 $^{\circ}$

Find angle x if line l is parallel to line m and line n is a transversal.

The correct option is D Interior angles on the same side of transversal are supplementary. x+ 50∘ = 180∘ x = 180∘ - 50∘ x = 130∘

The correct option is D

Interior angles on the same side of transversal are supplementary.
x+ 50 $^{\circ}$ = 180 $^{\circ}$
x = 180 $^{\circ}$ - 50 $^{\circ}$
