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.
first you must have the formula
now you just have to plugg in the numbers into the formula
solve for a
do it and then post your answer I will check if it is right
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
