Question

You need to spackle a hole on the outside of your house that is 24 feet off the

ground. You want to place the bottom of your ladder 7 feet from the wall. How tall
does the ladder need to be to reach the hole?
OA) 23 ft
OB) 25 ft
OC) 14 ft
QD) 20ft

Answer 1

The ladder needs to be 25 ft tall

Explanation:

You can use the pythagorean theorem for this:

a²+b²=c²

a = 7, b = 24, c = ?

We need to solve for c:

7²+24²=c²

49+576=c²

c²=625

c=25
