Question

Three angles of a quadrilateral are of measure 20°, 90° and 90°. Fourth angle is-

Answer 1

Answer:

160 dud

Step-by-step explanation:

90 +90 +,20 = 200

360-200=160

Answer 2

Answer:

Since, we know that total sum of degrees of quadrilateral is 360 degree

Let the fourth angle be x

Therefore, 20 degrees + 90 degrees + 90 degrees + x degrees =360 degrees

Therefore x degrees = 360 - 20 -90-90

=360 -200

=160

Hence , 160 degrees is the fourth angle
