right angled triangle: height of 324 and an adjacent of 54, a hypotenuse of 328.5, find angle of hypotenuse and adjacent
The angle opposite the hypotenuse has 90°.
The angle opposite the 54 side has an angle: tan(x°) = 54/324 or x° = tan-1(54/324).
The size of the other angle can be found be subtracting the above answer from 90°.
