A firefighter sees a woman trapped in a building 47 feet up from the bottom floor. If the firefighter is parked 43 feet away from the bottom of the building, at what angle of elevation, to the nearest degree, should the firefighter extend the ladder to reach the woman?

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.

first the equation needs to be simplified. so the equation would now look like:   52-24+11

then you multiply.

and when you multiply, you will get the answer of 39.  

hmmm. negative and positive numbers with equtions like this. i dont get it
