    *Pythagorean Theroem: a^2 + b^2 = c^2

    *The "c" variable represents the hypotenuse (largest number).

    First: substitute the numbers with the corresponding variables.

    50^2 + 70^2 = c^2

    50*50 + 70*70 = c^2

    2500 + 4900 = c^2

    7400 = c^2, or c^2 = 7400

    Sec: eliminate the exponent - find the square root of both sides.

    √c^2 = +/- √7400

    c = +/- √(2*2*2*5*5*37)

    c = +/- 2(2)(5)√2*37

    c = +/- 20√74 or, c = +/- 86.02

    *The hypotenuse has to be larger than 60.

    all angles of a triangle have to add up to 180

    therefore 180-70-50 =60

    c=60

    c=60

    with the following details you gave, it still needs a third parameter like is it a right triangle or what for you to find the third measure of the tiangle.
