The given information is:

We know the measure of two sides and one angle.

We can apply the Sine Rule to solve this problem. This rule states:


\frac{\sin A}{\bar{BC}}=\frac{\sin C}{\bar{AB}}

If we replace the known values, we can solve for angle A as follows:


\begin{gathered} \sin A=(\sin C*BC)/(AB)=(\sin36\degree *24)/(31) \\ \\ \sin A=(0.59*24)/(31) \\ \\ \sin A=0.455 \\ \\ A=\sin^(-1)(0.455) \\ \\ A\approx27\degree \end{gathered}

The measure of angle A is approximately 27 degrees.
