Question

a 96 foot transmission tower casts a 72 foot long shadow. an anchor wire runs from the top of the tower to the tip of the shadow. a ladder is set up vertically 66 feet from the base of the tower so the top of the ladder touches the wire. what is the height of the ladder

Answer 1

63.5

Explanation:

they all form a triangle, and the formula for that is a²+b²=c²

a=96 b=wire c=72

96²+b²=72²

9216+b²=5184

-9216 -9216

b²= -4032

square root of -4032 = 63.5
