Theorem are all the formulas related to Right Triangles. With these formulas we can determine angle measurements and side lengths. Tan 15 degrees = Y/75 (opposite/adjacent) .26794 = Y/75 Y = 20 (approx.) = opposite side length Tan 25 degrees = Z/40 (opposite/adjacent) .466 = Z/40 Z = 19 (rounded to whole number) = opposite side length To find the last missing side (BC), use the Pythag. Theorem: 20 squared + 19 squared = c squared 400 + 361 = c squared 761 = c squared c = approx. 28 Did Triangular Puzzle Pre-Quiz Homework: Finish Triangular Puzzle Pre-Quiz
