A triangle cannot have both a right angle and an obtuse angle because the sum of the angles in any triangle is always 180 degrees. If a triangle has a right angle (90 degrees), the other two angles must add up to 90 degrees to satisfy this rule, making them both acute angles (less than 90 degrees). Conversely, if a triangle has an obtuse angle (greater than 90 degrees), the other two angles combined would not be able to make up the remaining 90 degrees needed to reach a total of 180 degrees. Therefore, a triangle cannot simultaneously have a right angle and an obtuse angle.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
