1) The hypotenuse of an isosceles right triangle is 8 cm longer than either of its legs. Note that an isosceles right triangle is a right triangle whose legs are the same length. Find the exact length of its legs and its hypotenuse.

2) The length of a rectangle is 9 m longer than its width and the area of the rectangle is 280 m2. Find the exact dimensions of the rectangle.

3) The first leg of a right triangle is 3 cm longer than its second leg. If the hypotenuse has a length of 8 cm, find the exact lengths of the two legs

  • Math -

    if the legs are x and the hypotenuse is h, then

    h^2 = x^2+x^2
    (x+8)^2 = 2x^2
    x^2+16x+64 = 2x^2
    x^2 - 16x - 64 = 0
    Now just use the quadratic formula

    If the width is w, then
    w(w+9) = 280


    If the shorter leg is x, then
    x^2 + (x+3)^2 = 8^2
