Question

I need help setting up an equation to find the value of x, then I need to explain my reasoning.

Answer 1

the two lines are parallel to each other '

so by using linear pair property

72 + (7x + 24) = 180

7x + 96 = 180

7x = 180 - 96

7x = 84

x = 84/7

x = 12

so the answer is x = 12 degrees'
