Answer: Lower right corner (aka southeast corner)
Any acute triangle has all three angles less than 90 degrees. A scalene triangle is one where all sides are different lengths.

Extra info:
- The top left corner has a right (90 degree) angle, so this is a right triangle. It is a right scalene triangle to be more specific.
- The top right corner is an isosceles acute triangle. It's isosceles because two sides are the same length (10 ft).
- The bottom left corner shows a scalene triangle that is also obtuse since the 102 degree angle is present.
