Answer: Scalene Right
=======================================================
Explanation:
The triangle is scalene because all three sides are different in length. Also, the angles are all different which is another piece of evidence of this.
The triangle is a right triangle because of the 90 degree angle. Often the term "right angle" is used in place of "90 degree angle".

Extra info (optional)
- We can rule out anything with "obtuse" in it because obtuse triangles are only when one angle is larger than 90 degrees; which is not the case here.
- We can rule out anything with "acute" because this triangle doesn't have all its angles smaller than 90.
- The triangle is not equilateral since we'd need all three sides to be the same (and all three angles to be 60).
- The triangle isn't isosceles because it needs exactly two sides to be the same length.
