Question

therr angle of quadrilateral are 90,110,70. find fourth angle

Answer 1

suppose fourth angle = x
since sum if a quadrilateral is 360,
x+90+110+70 = 360
x+270 = 360
x = 360-270
x = 90

So the answer is that fourth angle is 90 degree.

Hope it helps :)

Answer 2

The sum of all the angles of a quadrilateral is 360 degrees.
Now, 360-(90+110+70)=360-270=90 degrees
So the fourth angle is 90 degrees
