Task 2 (Assume diagram is not drawn to scale)Sohcahtoa Mountain has an altitude of 800m. It is one of several that form the Scalene Mountain Range. The mountain to the east of Sohcahtoa Mountain has a higher altitude. George Geometer was taking a break from skiing and was basking in the sun at the top of Sohcahtoa Mountain. He wondered how much higher the eastern mountain was. He was able to see down to the base of the mountain to a cabin (directly below the peak of the mountain) with an angle of depression of 41º and look up to the peak at an angle of elevation of 27º.Find out how much higher the eastern mountain is (to the nearest tenth of a meter) using the sketch below.
Show your work below to get full credit, then enter your final answer in the next question.

Task 3 Assume diagram is not drawn to scale; show all work in the show work screen below, then enter your final answers in the questions that follow.Timmy Tangent and Susie Sine are on opposite sides of the base on Eastern Peak Mountain. Between them is their base lodge, directly under the peak of the mountain, which is _______m tall (see Task 2).The angle of elevation for Susie (on the eastern base) to the top of the mountain is 70º, and for Timmy (on the western base) the angle of elevation of the top peak is 80º.

b) Double check your triangle side lengths in task 2 using the Pythagorean Theorem.I. SOHCAHTOA mountain ski resort is considering expanding the resort to include Eastern Mountain. If they installed a gondola from the peak of SOHCAHTOA mountain to the Eastern Peak, how far would the gondola line have to span to connect the two mountain peaks? (Round to tenth of a meter.)
