Answer:

6.43, scalene.

Step-by-step 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
