Hey!!
here is your answer >>>
As we have learnt, the sum of angles A and B is exterior angle ,
so,
angle B would be
( 52 + x ) = 110
x = 110 - 52
x = 58!.
angle B is 58°
Sum of all angles in a trinagle is 180!.
angle C would be ,
52 + 58 + c = 180
110 + c = 180
c = 70
angles C is 70° !.
Hope my answer helps!
