So angle
is in between sides 16 and 21.
Refer to the attachment for triangle diagram.
To find the length of opposite side, use cosine rule as follows

From the diagram, 
Substituting the values in the formula,

Simplifying,


Taking square root on both sides,


Therefore length of third side is 31.49
