Question

In an isosceles triangle the base angle are twice it's vertical angles. Find the angle

Answer 1

Answer:let   the  vertices  angle  be  x

then the  base  angle  is  2x  

but  the  both  base  angle  are  equal  then  both  are 2 x

ATQ  

1. sum  of  all  angle  of  the  triangle  is  180

• 2x+2x+x=180
• 5x=180
• x=36
• then  vertices  angle  is  =36
• base angle  is   72
