Answer 2

Answer:

70 degree and 110 degree

Step-by-step explanation:

Sum of internal angles of a quadrilateral is 360 degree

If two angles are 60 and 120,

sum of the angles of thr the quadrilateral can be given by 180 + 3rd angle + 4th angle = 360

thus 3rd angle + 4th angle = 180

let 4th angle be x

so, ATQ 3rd angle is x+40

so, x + x+40 = 180

Thus, x = 70

Hence the remaining two angles are 70 and 110
