For small theta, theta~=tan(theta) when theta is in radians. So the angle of a "ball" undergoing z_accel and y_accel hung on the end of a string makes with the verticle will be approximately -z_accel/y_accel radians. Converting to degrees, multiply by 180/pi=57.29, or 5.729 times the returned value.
