Hello,
We know the hypotenuse 22 ft,
the adjacent side 3 ft,
so the cosine of the angle we are going to search is 3/22
that's done cos α=3/22==>α=82.1625...°≈82.2°

Answer:
4 and 9
Step-by-step explanation:
t2-13t+36=0
factors of 36 are:
1,2,3,4,6,9,12,18,36
factors that add up to 13 are: 9*4
factorise the equation:
(t-9)(t-4)=0
t-9=0 ---> t=9
t-4=0 ---> t=4
