Question

A firetruck parks 25 feet away from a building. The fire truck extends its ladder 60 feet to the very top of the building. How tall is the building?

Answer 1

/2975

Explanation:

Pythagorean theorem = A^2 + B^2 = C^2

We already know C^2 (60 ft) and B^2 (25ft)

We need to find A^2

C^2 - B^2 = A^2

60^2 - 25^2

3600 - 625 = 2975

Find the square root of 2975

There is no whole number squared that equals 2975

Height of the building is square root 2975

Check statement

/2975+ 25^2

2975 + 625 = 3600

The square root of 3600 is 60^2

Making the statement true

A^2 + B^2 = C^2

A^2 = 2975

B^2 = 25^2

C^2 = 60^2

2975 + 25^2 = 60^2
