Question

does anyone understand this is so please help me.

Answer 1

Answer:

B) Alternate Exterior Angles

B) 45

Step-by-step 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.
