Thinking, Inquiry, Problem Solving: (9 marks) 1 1) An equilateral triangle has a side length of 7 cm. If a perpendicular is dropped from a corner, what is the length of the perpendicular? Give the exact value, not an approximation. Page 3 of 4 1+ tan x 12) Prove that 1-tan x cos x - sin x [4) 13) Paul and Diana are both looking at the top of a tower in the distance in the same line of sight, although Diana is 100 m ahead of Paul. Paul observes the tower at an angle of 160 with the ground. If the top of the tower is 800 m from Diana, what is Diana's angle of sight with the ground? 800 m 160 = angle B 100 m K
