Answer:
100°
Step-by-step explanation:
Let the equal angles be x°
According to the angle sum property,
sum of all the angles of a quadrilateral = 360°
= 130° + 30° + x + x
160° + 2x = 360°
2x = 360° - 160°
2x = 200°
x = 100°

1 angle = 130°
2 angle = 30°
Total = 160°
Total measure of angels if a quadrilateral = 360°
360° - 160° = 200° ( remaning measure)
Since, other 2 angels are equal, me aayee if each of them = 200/2 = 100°
