Answer 1

To find the unknown side length in the given triangle, we can use the Pythagorean Theorem:

a^2 + b^2 = c^2

In this case, one side length is 12 and the other side length is 9, so:

12^2 + 9^2 = c^2
144 + 81 = c^2
225 = c^2

Taking the square root of both sides, we get:

c = √225
c = 15

Therefore, the unknown side length is 15.3.
