Hannah, Jennifer, Vivi, Citlalli, Astrid, and Lindsey are all at an apple farm picking apples off of a tree. Hannah bets them all that she can climb to the top and get the highest apple, which is 52 ft off the ground. If Astrid, Jennifer, Vivi, Citlalli, and Lindsey are 9 feet from the tree, what is the angle of elevation (theta) from the girls to Hannah in the tree?

 80.2 degrees

Kobe, Carter, Emory, Jackson, Josh, and Cameron are all out playing golf. Carter smashes a drive with an angle of elevation of 15 degrees. If the highest point of the drive was at 60 feet, how far was the ball when it was at 60 feet in the air? (Yes I am fully aware this won't generate a true right triangle. Draw it as though it were one.)

 224 feet

In triangle ABC, angle A is a right triangle. If tan of b = 8/9. Find cos b.

cos b = 9/12

200

In triangle ABC, angle A is a right angle. If Cos a = 12/17, find sin b.

sin b = 12/17.

300

In triangle ABC, angle A is a right angle. If sec b is 11/7, find tan b.

tan b = 8.49/7.

400
