how do i find the angle of elevation for both triangles?

You are riding the Ferris wheel at the fair. You look down at your friends in line for the next ride at an angle of depression of 40°. The Ferris wheel is 192 feet tall. What is the horizontal distance you need to walk to your friends when you get off the Ferris wheel? Show your work and round your final answer to the nearest tenth of a foot.

An old fashioned pirate ship departs from Pirate Island at a bearing of 30º. The ship  travels 30 km/h for 2 hours when it reaches Buccaneer Bay, where all of the treasure is buried. The ship drifts away from the bray for 4.5 hours at 12 km/h at an unknown bearing. While most of the pirates celebrate pirate things, the navigator wakes up from her nap and sees Pirate Island due East. The angle between the ship’s path and Pirate Island is 105.8º.   a. Find the bearing of the ship’s current location from Buccaneer Bay. b.Find the distance from the ship to Pirate Island.
