2 If AABC ADEF and a,c,x, are the lengths of BC, AB, YZ, and XY respectively. Use Algebra to show that if a/z=x/z then a/x-c/z 0.2 Solve for B to the nearest degree a) Cos B=3/8 b) Sin B=7/8 0.3 0.4 0.5 A ladder leaning against a wall at certain angles can be unstable. Some repair manual s recommend that the angle the ladder makes with the ground should be no more than 70 and no less than 60. If the base of an 8m ladder is placed 1.5m from the wall, is the ladder safe? Explain. Jasmine is planning to do some rock climbing. Before she scales of, she paces off 100m from the base of the cliff and sights the top with a clinometers. The angle of elevation to the top is 80. How high is the cliff? Show all your steps. In triangle PQR find the value of q, if R=73 Q=32 and r=23cm. 0.6 Draw a diagram to solve these problems. Beaver ton is 10km due east of Deerfield. Crow den is 8km NW of Beaver ton. How far is it from Crow den to Deerfield? Explain whether you have enough information to solve the problem.
