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.

Answer 1

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

Answer 2

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

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

Answer 3

a = 7?

Answer 4

Right! a = 7
