Answer 1

The answer would be the square root of 69 or 8.30662386

Explanation:

Use pythagoreum theorum

a^2 + b^2 = c ^2

13 = Hypotenouse

10 = a or b

10^2 + b^2 = 13^2

100 + b^2 = 169

-100

b^2 = 69

square root both sides

b = square root of 69 or 8.30662386

Answer 2

If you can turn to a decimal, then, 8.3 or 8.31 or square root of 69
