(1/3)x - 6 = 8
+6 +6
(1/3)x = 14
*3 *3
x = 42 is the answer :)
Let the base angle be x. If the obtuse angle is two and a half times the base angle, it will be 2.5x. In a triangle, all three angles will add up to 180. The third angle, the other base angle will be equal to x. So the equation will be:
x + x + 2.5x = 180
2x + 2.5x = 180
4.5x = 180
x = 40
If x = 40, then 2.5x = 100
