Answer:
B) Scalene Triangle
Step-by-step explanation:
This must be a scalene triangle because:
If it were a right triangle, there would be a right angle so A is out
If it were an equilateral triangle, all 3 angles would be equal to each other so C is out
If it were an isosceles triangle, 2 angles would be equal to each other so D is out
A scalene triangle consists of angles that add up to 180 degrees, but none of them are equal to each other. Therefore B is right.
