Answer 3

A trig question...

You have an angle....you have the side opposite that angle....and you want the hypotenuse of the triangle

What trig function uses Opposite and Hypotenuse?

Answer 4

sine?

Answer 5

Indeed^

\[\large sin\theta = \frac{\text{Opposite}}{\text{Hypotenuse}}\]

So here we just plug in the numbers... we know the angle is 27 and the opposite is 11 so

\[\large sin(27) = \frac{11}{\text{Hypotenuse}}\]
\[\large \text{Hypotenuse} = \frac{11}{sin(27)}\]
