Jennifer, a construction project manager, is checking to make sure that where two block walls meet is square. The block mason has done the bottom row of each wall. One wall is 12 feet, and the other wall is 16 feet. She measures the distance from each end and finds that distance to be 20 feet. What does she know? Select all that apply. O The corner where the walls meet is 90°. O The corner where the walls meet is not 90°. O The hypotenuse of the right triangle she measured is 20 feet. O The hypotenuse of the right triangle she measured is 16 feet. O She will need to ask the block mason to change one wall. O She will be able to tell the block mason to continue each wall.

Ratios

A ratio is a comparison between two numbers of the same kind. It represents how many times one number contains another. It also represents how small or large one number is compared to the other.

Trigonometric Ratios

Trigonometric ratios give values of trigonometric functions. It always deals with triangles that have one angle measuring 90 degrees. These triangles are right-angled. We take the ratio of sides of these triangles.
