No need, remember it is a right triangle, means it has a 90 degree angle.
use arctangent to find the two acute angles:
.
.
Let x and y be the legs of the angle,
Choose whether x = 8 and y = 5 or x = 5 and y = 8,
The formula for getting the angle:
and
To check your solution, the sum of the interior angles of any triangle is 180 degree. So, 58 + 32 + 90 = 180
