Answer:
Length of other leg is 24 and length of hypotenuse is 25
Explanation:
Whenever we want to find the other two legs of right triangle we have to find such values which satisfies the pythagoras theorem
Here one side is 7
And pythagoras theorem says

c is hypotenuse,ais one leg and b is the other leg
We have given say a=7 and we have to find c and b
We can think of c as 25 and b as 24 will satisfy the pythagoras theorem

Hence, Hypotenuse is 25 and other leg is 24
