Math-CHECK PLEASE

Which of the statements is ALWAYS TRUE?
A-A right triangle is a scalene triangle.
B-An equilateral triangle is an isosceles triangle.
C-An isosceles triangle is an obtuse triangle.
D-A right triangle is an acute triangle.
I got either A or D. I don't know.

Also, if angle A is 26.5, angle B is 3 times angle A, would angle C be 74, and would the triangle be a scalene?
