Question

If the vertical angle of an isosceles traingle is 130 degree. What are its base angles?

====================================


⊙ As the two sides of an isosceles triangle are equal so it's two angles touching the base are also equal.


So, we will take it as X

⊙ 2x+130=180

2x=50

x=50/2=25°

so, it's two base angles measure 25° each
