First find numbers that the denominator and the numerator can both be divided with. Such as 3, now 6/3=2 and 9/3=3. So basically it is 2/3. 6/9 simplify to 2/3.
X is a element of all real numbers but there is a vertical asymptote at x=o. Mathematically: XeR, x≠0
52/36 = 1.444444444
19/75 = 0.2533333333
Now lets add them :)
1.444444444 + 0.2533333333 = 1.697777778

Convert the angle into degrees so we can easily at what quadrant it lies
-11pi / 18 ( 180 / pi)= -110 degrees
to make it a positive angle add 360
-110 + 360= 250 degreesso it is in quadrant III
so the reference angle for quadrant III250 - 180= 70 degrees is the reference angle
