Solving Right Triangles

Vocabulary Solve a right triangle – to determine the measures of all six parts (3 angles, 3 sides).

Inverse Trig Ratios We use the inverse sine, inverse cosine, and inverse tangent if we are trying to find angle measures. The calculator buttons look like this: sin-1 cos-1 tan-1

Example 1 Find the acute angles of the triangle. Round to the nearest tenth.

Try This! Find the acute angles of the triangle. Round to the nearest tenth.

Example 2 Solve the right triangle.

Try This! Solve the right triangle.
