A ladder that is 13 feet long leans against a building. The bottom of the ladder is 5 feet away from the base of the building. How far up the side of the building does the ladder reach?
18 ft
16 ft
12 ft
\
8 ft*****
nope,
Use Pythagoras ...
x^2 + 5^2 = 13^2
etc
X=16 PLZ HELP
nope.
it is a right triangle;
x^2+5^2=13^2
x^2=169-25
x^2=144
solve for x
No. I don't know how you got 16.
Please use the Pythagoras Equation that Reiny posted.
We've checked two of your guesses. Do not post this problem again.
18 FOR SURE =RIGHT MRS.SUE

I AM SO SORRY EVERY TIME I COME OUT WITH 8
You haven't solved this. Do you understand it?
x^2=144
solve for x
