Questions:
1. Mr. Britz needs to support the tower with cables into an anchor in the ground 9 m from the base
of the tower. When the tower’s shadow is 9 m long, Mr. Brtiz’s shadow is 0.6 m long. If Mr. Britz
is 1.85 m tall, how long of a cable will he need to support the tower?
K:2, T:2, C:2, A:2
2. Explain in your own words why you are able to find the length of the cable with the information
you were given.
K:0, T:1, C:1, A:0
3. How much further does the plane need to fly to be directly above the ship? K:1, T:0, C:1, A:1
4. Solve for all unknown sides and angles in the triangle below. It will help to label the triangle’s
vertices and sides that are unknown with letters.
