Answer 1

142

Explanation:

∠2=38 ( corresponding angles)

definition: the angles which occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are equal.

sum of straight angle=180

∠5+∠2=180

∠5+38=180

∠5=180-38=142 degrees

Answer 2

the answer is 142.
180 - 38 is 142
