1. Lesson 6: Solving Problems with Triangles
LG: I can use my knowledge of right triangles and obtuse triangles to solve problems using SOHCAHTOA, Sine Law and Cosine Law

2. Strategies to Solve Triangles

3. Example 1 - Construction
A triangular roof has side lengths of 12 ft and 15 ft 9 in. I
If the roof is 22 ft across, determine the height of the support beam required (y).
15 ft 9 in
12 ft y
22 ft

4. Example 2- Navigation
The angle of elevation to the top C of a building from two points A and B on level ground are 50 degrees and 60 degrees respectively. The distance between points A and B is 30 meters. Points A, B and C are in the same vertical plane. Find the height h of the building

5. Practice
Pg # 6, 7, 12, 14, 16 (distance = speed x time)
