Question 351922


Let equal angles are x, x  and other is y.

according to question 

      y = 2x +12
 
now add all angles, 

x + x + y = 180

=> x + x + 2x +12 = 180

=> 4x + 12 = 180

=> 4x = 180-12
 
 =>  x = 168/4 = 42

then y= 2*42+12 = 96



so, angles of isosceles triangle are  42, 42 and 96.
