Use the Pythagorean theorem to solve:
a^2+b^2=c^2
144+b^2=256
b^2=114
b=10.58
The answer is 10.58 (rounded to nearest hundredth).
a^2+b^2=c^2
144+b^2=256
b^2=114
b=10.58
The answer is 10.58 (rounded to nearest hundredth).

If a right- angled one, then use the Pythagorean theorem to find the length.
16^2 + 12^2 = 256+144 = 400 = 20^2
16^2 + 12^2 = 256+144 = 400 = 20^2
