Answer:
see below
Explanation:
This problem could have 2 solutions
We could be given two legs
a^2 + b^2 = c^2
5^2 +13^2 = c^2
25+169 = c^2
194 = c^2
Taking the square root on each side
sqrt(194) = c
Or the 13 could be the hypotenuse
a^2 + 5^2 = 13^2
a^2 +25 = 169
a^2+25-25 = 169-25
a^2 = 144
Taking the square root of each side
a = 12
