Answer
There is no triangle which can be formed from these values.
Work Step by Step
First, we can only calculate the angle $B$ with the help of the Law of Sines:
$\frac{sin(A)}{a}=\frac{sin(B)}{b}$
$\frac{sin(60°)}{4}=\frac{sin(B)}{5}$
$sin(B)=1.083$
From this equation, we can get zero solutions, because the sine function can only have values of:
$-1\le\sin x\le1$
Therefore there is no triangle which can be formed from these values.
