Question

if one of the angles of quadrilateral are 45 75 and 140 . find fourth angle​

Answer 1

Step-by-step explanation:

100 is the fourth answer

because (45+75+140)-360 = 100

because the sum of the angles in a quadrilateral is 360

Answer 2

Answer:

100°

Step-by-step explanation:

Sum of angles of quadrilateral is 360.

Let fourth angle be n

Then,

45 + 75 + 140 + n = 360

n = 360 - 260 = 100

Fourth angle of quadrilateral = 100 degree
