Solve Right Triangles Mr. Funsch

Solving right triangles What you need to solve for missing sides and angles of a right triangle: 2 side lengths or A side and an angle

Inverse Trigonometric Ratios

Find the measure of angle C adjacent Ask yourself, “what 2 sides do I have?” Ask yourself, “what trig function should I use? Sine? Cosine? Or Tangent?” Set up the ratio Find the angle measure. opposite

Find the móC and móA

Solve the triangle

Solve the triangle

Solve the triangle

Assume the given angle is acute, find the angle measure to the nearest tenth sin A = 0.78
