LESSON 12.2 PROBLEM SOLVING WITH RIGHT TRIANGLES WORKSHEET ANSWERS

Repeat Step 2 using expressions involving j, sin C, and sin A. In order to find the distance along the northern branch, you need the measure of the third angle in the triangle. Label the height h. Add to collection s Add to saved. However, in this case you may find more than one possible solution.

Combine the two expressions by eliminating h. Label the length of the side opposite A as a, the length of the side opposite B as b, and the length of the side opposite C as c. If A is acute, it measures approximately Substitute the measurements and evaluate to verify that the proportion from Step 4 holds true for your obtuse triangles as well. However, in this case you may find more than one possible solution.

Lesson problem solving with right triangles worksheet answers

Use your knowledge of right triangle trigonometry to write an expression involving sin B and h, and an expression with sin C and h. Substitute the measurements and evaluate to verify that the proportion from Step 4 holds true for your obtuse triangles as well.

Add this document to saved. In order to find the distance along the northern branch, you need the measure of the third angle in the triangle. Use the transitive property of equality to combine them into an extended proportion: If A is acute, it measures approximately A lake between Teiangles A and C makes it difficult to measure the distance between them directly.

Combine the two expressions by eliminating h. Where along the northern branch should they dig for the treasure?

Measure the angles and the sides of your triangle. Label the length of the side opposite A as a, the length of the side opposite B as b, and the length of the side opposite C as c. What proportion do you get when you eliminate j? This is because two different angles—one acute and one obtuse— may share the same value of sine.
