Properties of right triangles.
- The benchmark will be assessed using MC (Multiple Choice) and FR (Fill in Response) items.
- Items may require the use of the Pythagorean Theorem, special right triangles, and relationships involving an altitude drawn to the hypotenuse of a right triangle.
- Items may require the use of the geometric mean.
- Radical expressions in multiple choice options will be in simplified or rationalized form.
In ABC, is an altitude.
What is the length, in units, of ?
Nara created two right triangles. She started with JKL and drew an altitude from point K to side JL. The diagram below shows JKL and some of its measurements, in centimeters (cm).
Based on the information in the diagram, what is the measure of x to the nearest tenth of a centimeter?
