Question

I would appreciate if someone could answer this :)

Answer 1

x = 3

Explanation:

(-2 + 40x) + 62° = 180° (adjacent angles are supplementary)

-2 + 40x + 62 = 180

Add like terms

40x + 60 = 180

Subtract 60 from each side

40x + 60 - 60 = 180 - 60

40x = 120

Divide both sides by 40

40x/40 = 120/40

x = 3
