The Great Pyramid of Cheops has a square base with a length of 756 feet. Its height is 482 feet. If you walk straight up from the center Of the north side to the top of the pyramid you have to climb an angle of degrees. You decide to simplify your life and walk up along one of the ridges. Thus you have to climb only at an angle of degrees. On your way up the ridge you walk a distance of feet. Hint: For the first two parts draw right triangles and use an inverse trig function. For the third part just use the Pythagorean Theorem.

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.

Question

1) choose two numbers to represent the length of the legs of a right triangle. Assign one of these values to a and the other to b. 2) use the Pythagorean Theroem to solve for the value of the hypotenuse, c 3) Label your right triangle, so that the angle opposite side a is angle A. The angle opposite side b is angle B. The angle opposite the hypotenuse is angle C but should also be your right triangle. Attach a picture of your triangle. 4) now find the exact values of the six trigonometric functions of angle A.
