You need three non-collinear points to name a plane.
Non-collinear means "not on the same straight line". So these three points can't all lie on the same straight line. If three points do lie on the same straight line, then it is impossible to generate a single unique plane.
Range increases. This is because range is the biggest number minus the smallest number. So when the biggest number is much bigger than the rest of the numbers, the range increases.
That would be 100 * sin 30 = 100 * 0.5 = 50 pounds
