Answer:
Option (A)
Step-by-step explanation:
By applying the theorem angle theorem in the given triangle,
Sum of exterior angle of a triangle is equal to the sum of opposite interior angles of the triangle.
Therefore, 130° = y° + y°
130° = 2y°
y =
y = 65°
Therefore, measure of interior angles 'y' of the given triangle will be 65°.
Option (A) will be the answer.
