de​

Answer 1

Step-by-step explanation:

43+95+147+x=360...........(the sum of angles in quadrilateral

is 360)

285+x=360

x=360- 285

x=75°

Answer 2

Answer:

75 degree

Step-by-step explanation:

sum of all interior angles  in a quadrilateral = 360

let the unknown angle be x

so,

43 + 95 +147 + x = 360

x = 360 - ( 43 + 95 + 147 )

x = 360 - 285

x = 75

so the unknown angle is 75 degree
