As seen in the picture above, I am trying to get an angle from the bno055 IMU but when I run the arctan function it doesn't reveal the angle. What am I doing wrong?
I do not think atan() a built in function. Maybe:
Angle = val * 180 / PI;
If you post code as a picture then people can't try it themselves. Always post code correctly.

Have you tried atan2()
atan() returns the angle in radians
as @Grumpy_Mike pointed out look at atan2()
Thanks for the help but it says it is expecting two values for atan2() what would those be?

Why might the ratio of two orientation angles, about different axes, be useful or interesting?
double val = euler.y()/euler.x();
