Calculator A firefighter's ladder leans 50 feet up against a
building and is positioned 50 feet away from the
building along the ground. The base of the ladder
makes a 45° angle with the ground. Use a
calculator to find the decimal approximation for
cos T. Round to three decimal places.

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

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.
