Question

ABCD is a quadrilateral in which angle A is equal to 50 degree angle b is equal 200 degree angle C is equal to 70 degree and Angle d​

Answer 1

Answer:

40

Step-by-step explanation:

Let d=x

200+50+70+x=360 (Sum of all interior angles in quad. is 360)

320+x=360

x=40

So d=40

Answer 2

Answer:

Angle sum of quadrilateral = 360°

Let the measure of angle D be x

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

50° + 200° + 70° + x = 360°

320° + x = 360°

x = 360° - 320° = 40°

40° is the measure of angle D.
