Answer:
√104 in
Explanation:
Well to start off we can use Pythagorean's theorem ~ A^2 + B^2 = C^2
in this case we will indirectly use this formula. Now we know this; A^2 + 11^2 = 15^2
Let's start using some algebra now B )
A^2 + 121 = 225 > A^2 = 225 - 121 > A^2 = 104 > A = √104
Which is the answer. ALso if you're the brainy type and want to know how to simplify this even further...
Can the Square Root of 104 Be Simplified?
104 can be simplified only if you can make 104 inside the radical symbol smaller. This is a process that is called simplifying the surd. In this example, the square root of 104 can be simplified.
√104 = 2√26.
