HELP WITH THIS MATH QUESTION!!! I DONT KNOW HOW TO DO THIS

The similarity relationship is AC / EC = AB / ED.
The length of AB is 157.50m.
When two triangles are similar, the ratio of the known sides of the triangles can be used to determine the length of the side of the unknown length.
The similarity relationship is : AC / EC = AB / ED
AC = 160 + 50 = 210
210 / 160 = AB / 120
AB = (210 X 120) / 160 = 157.50
