Question

Does anyone understand this is so please help me.

Answer 1

B) Alternate Exterior Angles

B) 45

Explanation:

For the first problem, these angles are known as alternate exterior angles because they are on opposite sides of the transversal and they are outside the parallel lines. Therefore, B is correct.

For the second problem, alternate exterior angles are congruent, so we set both sides equal to each other and solve for x:

`m\angle1=2x+38,m\angle8=128^\circ`

`2x+38=128`

`2x=90`

`x=45`

Therefore, B is correct.
