Q: Pre-AP Geo: GF CA Trigonometry "F" Test

While at an Australian zoo, a kid spots Forest the tallest giraffe. Using the dimensions shown in the figure, how tall is Forest? Round to 1 decimal place.

My dog, Rascal, is playing in the park and sees a tree away. Since he is the dog of a mathematics teacher, he knows how to calculate the angle of elevation to the top of the tree where he sees a cat. Find the horizontal distance between Rascal and the tree (x). (Round your answer to 1 decimal place.)

If chord BC is 64 cm, what is the length of the diameter of the circle? (Round your answer to 1 decimal place.)

What is the height of the tree from the ground to the top? (Round your answer to 1 decimal place.)

What is the length of GI? (Round your answer to 1 decimal place.)
