A wind-swept tree grows at an angle of 85°. An environmental scientist wants to know the height of the tree. She walks 50 m from the tree and measures the angle of elevation of 40° to the top of the tree. How tall is the tree? 40° B 85° 50 m Milena, Jared and Brennan have 3 different approaches to answering this question. Milena suggests using the tan ratio to solve for the height of the tree. Jared says we should use sine law to solve for the height of the tree. Brennan want to use cosine law sinse this is a SAS triangle. Blank 1: Who is correct? Blank 2: What is the height of the tree? Round your answer to the nearest tenth of a metre.
