Question

Question 7 Indicate the answer choice that best completes the statement or answers the question ALGEBRA Find the value ofr in each figure.

Answer 1

Question 7. These angles are supplementary

29 + (x - 5) = 180

x - 5 = 180 - 29

x = 151 + 5

x = 156°

Question 8.

7x + 110 = 180

7x = 180 - 110

7x = 70

x = 70/7

x = 10

Question 9.

72 + (x + 4) = 180

x + 4 = 180 - 72

x = 108 - 4

x = 104°

Question 10.

49 + (x + 3) = 90

x + 3 = 90 - 49

x + 3 = 41

x = 41 - 3

x = 38

Question 11.

x + 92 + 78 = 180

x = 180 - 92 - 78

x = 10

Question 12.
