Question 1123748: in isosceles triangle, the number of degrees in the vertical angle is to the number of degrees in each base angle as 10:9. Find vertical angle.
Answer by Alex.33(110) (Show Source): You can put this solution on YOUR website!
Vertical Angle(v)/Base Angle(b)=10/9
b=9v/10
v+2b=180.
solve for v: v=450/7 deg.=64.29 deg(approximately).
