Question

Find the value of x. Thank you for helping :)

Answer 1

x=16

Explanation:

125=45+5x (vertically opposite angles)

5x=125-45

5x=80

x=80\5

x=16

Answer 2

x= 16°

Explanation:

125°= 5x +45° (vert. opp. ∠s)

5x= 125° -45° (bring constants to 1 side)

5x= 80° (simplify)

x= 80° ÷5

x= 16°

*The angles that are opposite each other when 2 lines intersect are equal. (focus on the big x)
