Question

The original height of the Great Pyramid of Giza was 481 feet. The side of the pyramid rose at an angle of approximately $52^{\circ}$. Which of the following correctly uses the sine ratio to find the length from the bottom to the top of the pyramid to the nearest foot?Answer Choices610 feet781 feet379 feet296 feet

Answer 1

Let x be the slanted length. Then sin(52°) = opposite/hypotenuse = 481/x, so x = 481 / sin(52°) ≈ 481 / 0.7880 ≈ 610.

Answer: 610 feet.
