LG: I can use my knowledge of right and oblique triangles to solve problems

Strategies to Solve Triangles

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 fty

22 ft

Example 2- NavigationThe 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
