20. You can estimate the height of a flagpole by placing a
mirror on level ground so that you see the top of the
flagpole in it. The girl shown is 172 cm tall. Her eyes
are about 12 cm from the top of her head. By measurement,
AM is about 120 cm and A'M is about 4.5 m. From
physics it is known that 21 = 2 2. Explain why the
triangles are similar and find the approximate height of
the pole.

Consider the triangle below. Click on the picture to see it more clearly. In questions 1, 2 and 3 below, you are given 2 sides of a triangle and an angle opposite one of the sides. This is the so called "ambigous" case since it can give 0 triangles, 1 triangle or 2 triangles. In each case determine the number of triangles possible with the given parts. (enter 0, 1 or 2) 1. a = 8, b = 12, A = 50° number of possible triangles: 2. a 13.6, b = 12, A = 41° number of possible triangles: 3. a 17.2, b = 25, A = 34° number of possible triangles: 9. 9.
