Answer 2

Step-by-step explanation:

l// m and t is a transversal then

// m and t is a transversal thenif two parallel lines intersected by a transversal then the exterior angles on the same side to the transversal are supplementary.

// m and t is a transversal thenif two parallel lines intersected by a transversal then the exterior angles on the same side to the transversal are supplementary.=>2x-10+5x-20=180°

// m and t is a transversal thenif two parallel lines intersected by a transversal then the exterior angles on the same side to the transversal are supplementary.=>2x-10+5x-20=180°=>7x-30=180°

// m and t is a transversal thenif two parallel lines intersected by a transversal then the exterior angles on the same side to the transversal are supplementary.=>2x-10+5x-20=180°=>7x-30=180°=>7x=180°+30°

// m and t is a transversal thenif two parallel lines intersected by a transversal then the exterior angles on the same side to the transversal are supplementary.=>2x-10+5x-20=180°=>7x-30=180°=>7x=180°+30°=>7x=210°

// m and t is a transversal thenif two parallel lines intersected by a transversal then the exterior angles on the same side to the transversal are supplementary.=>2x-10+5x-20=180°=>7x-30=180°=>7x=180°+30°=>7x=210°=>x=210°/7

// m and t is a transversal thenif two parallel lines intersected by a transversal then the exterior angles on the same side to the transversal are supplementary.=>2x-10+5x-20=180°=>7x-30=180°=>7x=180°+30°=>7x=210°=>x=210°/7=>x=30°

The value of x is 30°
