Hi,

One of the base angles of an isosceles triangle is 2 degrees more than 5 times the vertex angle 

find the angles; base angle 



Isosceles Triangle, Base angles are equal

 (5x+2) + (5x+2) + x = 180°    |Note:  Sum of the angles in a Triangle = 180° 

       11x = 176

         x = 16°  and the Base Angles are 82°    

CHECKING our answer***

 16° + 82° + 82° = 180°
