Question interpreted as:
ABC is a right triangle right angled at A.
BC=17 feet
angle C = 35 degrees.
AC=BCcos(35)=17*0.8192=13.93 feet to the nearest 1/100th of a foot.
(20+2.5)x = cost
when x equals number of tickets
(20+2.5)24 = 540
I think the correct one is That is a right triangle despite the fact that you did not give full information.
