Answer:
{2, 8}
Step-by-step explanation:
We want to find x for ...
15 = 4|x -5| +3
12 = 4|x -5| . . . . subtract 3
3 = |x -5| . . . . . . divide by 4
±3 = x -5 . . . . . . show the meaning of absolute value
5 ±3 = x = {2, 8} . . . . . add 5
The values of x for which f(x) = 15 are 2 and 8.
Could you show the problem? I am also bad at math but showing the whole problem might give you the right answer

Hope it will help :)
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
