each base angle of an isosceles triangle has a measure that is 20 more than three times the meausre of the vertex angle. find the meausre of the vertex angle
--------------
Let vertex angle have measure "x".
Each base angle is 3x+20
-------------------------------
EQUATION:
3x+20 + 3x+20 + x = 180
7x = 140
x = 20 Degrees (measure of the vertex angle)
