Remember "SOH CAH TOA"


Sine = (Opposite/Hypotenuse)

Cosine = (Adjacent/Hypotenuse)

Tangent = (Opposite/Adjacent)


In this case, we will be using cosine, and our equation will be \frac{cos(28)}{1} =\frac{11}{x}


So firstly, cross-multiply. cos(28)*x=11


Next, divide both sides by cos(28), and your answer will be x=12.5
