If you have a slide rule or a trig table look for the closest value to 15/8 then see the corresponding angle value. (You might have to interpolate between the two closest values for the precise fraction of an angle). If you have a scientific claculator enter inv tan (15/8) to see the answer.
If you just want someone to tell you the answer you're out of luck here. I know but I'm not telling.

The way you wrote this equation X can be for degrees or radian measure. For Degree you can use a calculator in degree mode and use the [ INV tan] (15/8). Be careful for if you are in radian mode your answer will be 1.08083. If this is the case multiply by 180 then divide by pi. either way your answer should be 61.92751. If all else fails go to a trig table and look for the tangent number 1.873 and read the degree which will be 61.9 -good luck

arctan (15/8)= 61.93
Type in 2ndF tan (15/8) on a calculator

Type on your calculator
15/8 = [inv or shift] [tan]
and you will know it is about 62 degrees

Everyone's right.... unless you are looking for the angle in radians. Better check the problem's instructions.
If it in in radians, just make sure your calculator is in radian mode first. Or, multiply any of the above answers by pi/180.
