(c) From (T) and your answers to (a) and (b) find the distances A13 and 3A2 . [2 marks] AlB : m. 3A2 : m. (d) Hence nd the distance A1A2 between the tips of the trees. A1A2 : ll The observer has measured the following values: a1 = 22, a2 = 33, d2 = 38 m, hi = 36 m. (+ ) In the following questions, round off your answers to 3 decimal places. (a) Find the height h2 of the second tree. h2 = m. [2 marks] (b) Find the distance dj between the observer and the first tree. d1 = m. [2 marks] In the same diagram, denote A1 the tip of the first tree, A, the tip of the second tree and B the point on the first tree at the height h2, as shown below:An observer is standing at the point 0 between two trees. The angles of the line of sight to the top of the trees are al and a2, the distances from the observer to the trees are d1 and d2, and the heights of the trees are hl and hg, as labelled in the diagram below. The observer has measured the following values: Perform the first 3 rewrites of the following L-Grammar. WO = XF ro : F - FX r1 : X - XF Write your answers in the boxes below.
