Question

For questions 7 and 8 find the unknown angle.

Answer 1

Answer: 7) 58 degrees 8) 71 degrees

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

Answer 2

58 degrees for Question 7, and 71 degrees for Question 8

Explanation:

For question 7:

180 - 99 = 81

81 + 41 = 122

180 - 122 = 58

For Question 8:

142 / 2 = 71
