Question

Find the value of X and the missing angle

Answer 1

x=10

Explanation:

8*10=80

80+3=83

83+97=180

Answer 2

x = 10

missing angle = 83°

Explanation:

These are supplementary angles meaning they have a sum of 180°.

8x + 3 + 97 = 180

8x + 100 = 180

8x + 100 - 100 = 180 - 100

8x = 80

x = 10

Substitute the value for the variable.

8(10) + 3

80 + 3

83
