First find x. The interior angles must add to 180.
(x+20)+(2x-10)+(3x+20)= 180
6x+30=180
6x=150
x=25

Now plug in the value of x to find each angle measure.
x+20
25+20
45

2x-10
2(25)-10
40

3x+20
3(25)+20
95

Because all angles are different measures, the triangle must be scalene. There is one angle greater than 90 degrees so it is obtuse.

Final answer: Scale and obtuse
