    Find the diagonal of a square that has sides of length 8. - ProProfs

    Find the diagonal of a square that has sides of length 8.

    • A

    • B

    • C

    • D

    • E

    Correct Answer
    A. C
    Explanation
    The diagonal of a square can be found using the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (diagonal) is equal to the sum of the squares of the lengths of the other two sides. In this case, the square has sides of length 8, so the length of each side is 8. Using the Pythagorean theorem, we can calculate the length of the diagonal as the square root of (8^2 + 8^2) = √(64 + 64) = √128 = 8√2. Therefore, the correct answer is C.

    A ladder leans up against a house at an angle of elevation of 60 degrees. If the ladder is 20 feet long, how high up on the house does the ladder reach? You may round to the nearest tenth of a foot. - ProProfs

    A ladder leans up against a house at an angle of elevation of 60 degrees. If the ladder is 20 feet long, how high up on the house does the ladder reach? You may round to the nearest tenth of a foot.

    • A

    • B

    • C

    • D

    • E

    Correct Answer
    A. B
    Explanation
    The correct answer is B. To find the height that the ladder reaches on the house, we can use trigonometry. The angle of elevation is given as 60 degrees and the length of the ladder is 20 feet. The height on the house can be found using the sine function, which is opposite/hypotenuse. So, the height on the house is equal to the length of the ladder multiplied by the sine of the angle of elevation. Therefore, the height on the house is 20 feet multiplied by the sine of 60 degrees, which is approximately 17.3 feet.
