Question

Hi there Ms or Mr could you please help me out here because i don't understand this problem

Answer 1

(3X+60) + 60 = 180 ( CONSECUTIVE ANGLES are supplementary)

Now, solve for x

3x + 60 + 60 = 180

3x + 120 = 180

subtract 120 from both-side of the equation

3x = 180 - 120

3x = 60

divide both-side of the equation by 3

x = 20
