We can use the Сosine formula to solve this problem.
<span>First we must find the third side (АС) of the triangle:
</span>

<span>
The smallest angle of the triangle lies opposite the smallest side, so we need to find m</span>∠C.

Now we can use Bradis's Table (I don't know the name in English, maybe Trigonometric Table?) to find m∠C:
m∠С = 38°42' = 38.7°
Answer: 38.7°
