I will assume that this is a right triangle and neither side length is the hypotenuse.
In the case that this is a right triangle and neither side length given is for the hypotenuse, you would use tangent to solve for your angle measure.
tan(Q) = the length of the side opposite of Q/the length of the side adjacent to Q.
So for this answer:
**NOTE: Side a is traditionally the side opposite to angle A.**
tan(A) = a/b *where b is not the hypotenuse
=>
tan(A) = 76.4/39.3
tan(A) = 1.94402...
A = arctan(1.94402...) *arctan is the same thing as inverse tangent or tan^(-1)
A ~= 62.78 Degrees * ~= means approximately.
***Extra stuff:
tan = opposite/adjacent
sin = opposite/hypotenuse
cos = adjacent/hypotenuse
