Answer:

20u

Step-by-step explanation:

The Pythagorean Theorem is a good resource for this question. The pythagorean theorem is only used for right triangles. This formula is comprised of a^2+b^2=c^2, a and b are the two legs of the triangle and c is the hypotenuse which will always be the longest leg on the triangle. In this case we could type into our calculator 12^2+16^2=400 we then take the square root of 400 which is 20.
