    If any lovely person would be so kind as to help me out, I'll love them forever.

    What is the length of the longer leg of a 30-60-90 triangle with the hypotenuse of length 24 square root of 3 meters squared?

    If the area of a square is 225 cm squared, what is the length of the diagonal?

    What is the length of the hypotenuse of a right triangle with legs of length 80 ft and 150 feet?

    Find the circumference of a circle inscribed in an equilateral triangle with a height of 12 square root of 3 in.

    Find the area of an equilateral triangle with sides measuring 6 meters.

    Is triangle ABC with vertices A(2,4), B(10,2), and C(7,7) scalene, isosceles, or equilateral?

    The longest side is the hypotenuse.

    Area = length squared, so the length must be 25. Use this value with pythagoras thm to determine the diagonal

    Use pythagora's thm, it says, the hypotenuse squared equals the summed squares of the remaining sides.

    These are all simple applications of the Pythagorean Theorem. Look it up if necessary, and If you really can't figure it out, show us what you've tried.

    Form some line segments connecting the center of the circle to the vertices of the triangle and to the midpoints of its sides. Then you should be able to use the newly-formed right triangles to determine some of the needed lengths. The main thing you're looking for is the radius of the circle, so that you can use your circumference formula.

    Split it into two right triangles. Use the Pythagorean Theorem again.

    To determine what kind of triangle you have, you should start by determining the lengths of the sides. How do you find the distance between two points?

    Not quite. I guess you misread that as 625.
