For questions 7 and 8 find the unknown angle.

Answer:
58 degrees for Question 7, and 71 degrees for Question 8
Step-by-step explanation:
For question 7:
180 - 99 = 81
81 + 41 = 122
180 - 122 = 58
For Question 8:
142 / 2 = 71
Answer: 7) 58 degrees 8) 71 degrees
Step-by-step explanation:
7) 41 + x = 99 degrees (the two interior opposite angle is equal to the exterior angle)
subtract 41 on both sides
x = (99 - 41) degrees
x = 58 degrees
8) x + x = 142 degrees
2x = 142
divide 2 on both sides
x = 71 degrees
