Question

In quadrilateral ABCD, angle A + angle B = 150. Then angle C + angle D = ___​

Answer 1

Step-by-step explanation:

as sum of angles in as quadrilateral is 360 degree

angle A+ angleB + angle C +angleD =360

150+ angle C +angleD=360

angle C +angleD=360-150=110

Answer 2

Step-by-step explanation:

By angle sum property of quadrilateral:-

angle A+ angle B+ angle C+ angle D = 360°

150° + angle C + angle D = 360°

angle C + angle D = 360°- 150°

angle C + angle D = 210°
