    8.2 Trigonometric Ratios Trigonometry Part 1: Finding Missing Sides Practice

    Directions: Express each ratio as a simplified fraction. 1) Find sin P, cos P, tan P. 2) Find sin L, cos L, tan L. 3) Find sin X, cos X, tan X. 4) Draw a 45-45-90 Δ. Label the smallest 5) Draw a 30-60-90 Δ. Label the smallest side 1 and then find all missing sides. side 1 and then find all missing sides. Then, write tan45° as a simplified fraction. Then, write cos60° as a simplified fraction.

    6) Directions: Use a calculator to find each value. Round each answer to the nearest hundredth. sin57= cos60= cos33= tan30= tan45= sin85=
