Answer:
x= 16°
Step-by-step explanation:
125°= 5x +45° (vert. opp. ∠s)
5x= 125° -45° (bring constants to 1 side)
5x= 80° (simplify)
x= 80° ÷5
*The angles that are opposite each other when 2 lines intersect are equal. (focus on the big x)
x=16
125=45+5x (vertically opposite angles)
5x=125-45
5x=80
x=80\5
