To simplify this expression, we will first need to use the double angle identity for sine:
sin(2θ) = 2sin(θ)cos(θ)
Given that sin(2260) = sin(1130 + 1130), we can rewrite the expression as:
(21 sin(1130)cos(1130)) / 2sin(1130)cos(1130)
We can now simplify to get:
21 / 2 = 10.5
Therefore, the simplified expression is 10.5.
