Let each of the equal angles are x
So
x+x=105(exterior angle property)
2x=105
x=105/2
x=52.5°
So
x+x=105(exterior angle property)
2x=105
x=105/2
x=52.5°

ans is 52.2°
if exterior angle = 105°
then,
interior angle
=sum of all the angles of the triangle- exterior angle
=180°-105°
=75°
as the two interior angles are equal
∴ let it be x
75°+ 2x =180°
180°-75°=2x
105= 2x
∴ x=105÷2
∴ x= 52.5°
