Answer:
Therefore, the length of third side is 28 and it is a leg.
Explanation:
Given that,
The length of two sides of a right angle triangle are 96 and 100.
Three sides of a right angle triangle form Pythagorean triplet.
Now,
The square of 96 is 9216, and the square of 100 is 10000.
∵
and

⇒

since, square root of 784 is 28.
According to pythagorean theorem, it states that sum of the square of base and square of perpendicular is equal to square of hypotenuse.
Here,

⇒

⇒

⇒

∴ The length of base (leg) is
.
Therefore, the length of third side is 28 and it is a leg.
