The distances from John to the trees are 50 m and 35 m, and the angle between the two trees from John's perspective, is 67. How far apart are the trees, to the nearest centimetre? Include a labelled diagram in your solution. [A 3] [C 1] 6. A boat is approaching a cliff which is 50 m tall. If the angle of elevation from the boat is 60 , how far away is the boat from the cliff?

Given APOR, OR = 5.6 m and S is the midpoint of QR. Determine PQ, to the nearest tenth, if LPSQ = 330 and 4 PRO = 220. Include a diagram. [3] P 330 22 0 2.8 m 2.8 m R 15. Explain when an ambiguous case might exist. Include all necessary conditions. As part of your explanation, provide examples (including a diagram) of possible given value that would result in an ambiguous case. You do not need to solve your own examples. [6C] B B 16. Emma is on a 50 m high bridge and sees two boats in the water below her. Emma estimates the angles of depression to be 38 for boat A and 350 for boat B. How far apart are the two boats if the angle in between Emma's lines of sight of the two boats is 110. Draw a diagram as part of your solution. Solution 350 Property of CanSTEM Educa
