Answer:
C
Step-by-step explanation:
A is impossible. You cannot have both a right triangle and in the same triangle have an angle in it that is over 90 (that's the meaning of scalene)
B is sort of true, but only sort of. All scalene triangles have an angle over 90 and 2 acute angles.
C this is the answer to the question. It has 1 right angle and 2 equal sides. The two equal sides make it isosceles and the right angle is given.
D an acute triangle has three angles under 90 that add to 180. Not the right description.
