If you are not told it is a right triangle, there is no way to find the leg of either of the two sides (adjacent sides) that form that angle.

If it is a right triangle, the adjacent measures .
There is another adjacent side, the hypotenuse, that measures .

In a right triangle with a angle, the other acute angle also measures ,
so it is an isosceles right triangle, with two sides of equal length (the legs) opposite the two angles.
From the point of view of one of the two angles,
one of the legs is the opposite leg,
and the other (equal length) leg is the adjacent leg.
