Answer:
6.43, scalene.
Explanation:
assuming that those are meant to represent the angles in the triangle,
6x + 30 + 7x + 15 + 8x = 180
21x + 45 = 180
21x = 135
x = 6.43
The triangle is not equalateral because the angles would all be the same, it isn't isosceles since 2 aren't the same, it must be scalene since all 3 angles are different
