Wee ooh wee ooh! The firefighters have arrived on the scene of a building fire. They know that the fire is on the 3rd floor which is 45 feet off the ground. The fire truck can safely get 15 feet from the building.

How far do they need to extend the ladder to reach the window?

im with everythinglos so yeahhhhh

step-by-step explanation:

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
