Hello!
The degrees around a circle is 360°
We add all the values to get what x is
8x - 10 + 6x + 10x + 10 = 360
Combine like terms
24x = 360
Divide both sides by 24
x = 15
Now we put x into the 3 equations to find what the triangle is
8(15) - 10 = 110
6(15) = 90
10(15) + 10 = 160
Since the sides are unequal the triangle is a Scalene triangle
The answers are x = 15 and it is a Scalene triangle
Hope this helps!
