Posted by on .

a and b are both the lengths of the legs of a right triangle, c is the length of the hypotenuse. Find the missing length if b=24 and c=25. I don't know how to do this.

  • algebra - ,

    first you must have the formula
    a^2+b^2=c^2
    now you just have to plugg in the numbers into the formula
    a^2+24^2=25^2
    solve for a
    do it and then post your answer I will check if it is right

  • algebra - ,

    You'll need to plug these lengths in this theorem:

    a^2 + b^2 = c^2
    a^2 + 576 = 625
    a^2 = 49
    a = ?

    a = 7?

    Right! a = 7
