Answer: 7.9

Explanation

What is given is 2 angles (44 and 90), one side, 11, and are asked to find another side.

In this case we may use the sin rule:

sin 1/ side1 = sin 2/ side2, where the sides are opposite to their respective angles.

The angle opposite of x is the only angle remaining in the triangle, so we can easily find it by 90-44 = 46, since it is a right triangle.

So now we can apply the sin rule:

1) sin46/x = sin90/11
2) 0.71934/x = 1/11
3) x = 0.71934 x 11
4) x ≈ 7.91274

x ≈ 7.9

Hope this helps :)
