Chandra has a ladder that is 20 feet long. If the top of the ladder reaches 16 feet up the side of a building, how far from the building is the base of the ladder? (use Pythagorean Theorem)

12 feet

Step-by-step explanation:

when you have c (the hypotenuse) and a (the opposite side) but you need to find b (the base) you have to flip around the theorm from a^2 + b^2 = c^2 to c^2 - a^2 = b^2.

then you plug in your numbers: 20^2 - 16^2 = b^2

then you solve the exponents: 400 - 256 = b^2

and subtract: 144 = b^2

lastly you square root both sides to get your 12 = b

hope this helped :))

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
