the diagonals of an isosceles trapezoid are each 17,the altitude is 8,and the upper base is 9.Find the perimrter of the trapezoid.

  • Math -

    Hint: If the diagonals are equal, then it must be an isosceles trapezoid.
    Construct altitudes from the ends of the side of 9 units
    You should be able to see right-angled triangles with hypotenuse of 17
    (you should get a length of 21 for the other base and 10 for the length of the other two sides.)
