Answer:

m∠7 = 142°

straight line's degree measurement = 180°

Then get the adjacent angle of 38. Subtract 38 from 180:

180 - 38 = 142

m∠7 = 142°

Hope this helped

Answer:

m∠7 = 142°

Explanation:

Note that a straight line's degree measurement = 180°

Note that the angle directly next to (to the left of) m∠7 has a measurement of 38°. Subtract 38 from 180:

180 - 38 = 142

m∠7 = 142°
