Answer:

4

Explanation:

This is a right triangle, so you can use the Pythagorean Theorem.


a^(2) +
b^(2) =
c^(2) C has to be the longest side. In this case, that is 5


a^(2) +
3^(2) =
5^(2)


a^(2) + 9 = 25 Subtract 9 from both sides


a^(2) + 9 - 9 = 25 - 9


a^(2) = 16 Take the square root of both sides.


\sqrt{a^(2) } =
√(16)

a = 4
