(a)

Answer to Problem 51PPS
Explanation of Solution
Given :
A pirate ship ride follows a semi-circular path.
Calculation:
We need to find the measure of arc AB.
Since the arc AB is minor arc and the ship ride is a semi-
So,
measure of arc AB =
So, measure of arc AB is
(b)
Find the length of arc AB.

- Can someone help me with this please?arrow_forwardMariela is in her classroom and looking out of a window at a tree, which is 20 feet away. Mariela’s line of sight to the top of the tree creates a 42° angle of elevation, and her line of sight to the base of the tree creates a 31° angle of depression. What is the height of the tree, rounded to the nearest foot? Be sure to show your work to explain how you got your answer.arrow_forward1arrow_forward
