Question

In a Quadrilateral ABCD< A=50 <B=80 <C=130 degrees, Find angle D is????​

Answer 1

Answer:

Angle is equal to 100 degree

Step-by-step explanation:

apply angle sum property of quadrilateral

sum of all angles of quadrilateral is 360 degree

Answer 2

Answer:

Here ∠BDC=∠BAC=50

∘

since angles in same segment are equal

In △BCD, we have

∠BCD=180

∘

−(∠BDC+∠DBC)

=180

∘

−(50

∘

+60

∘

)

=180

∘

−110

∘

=70

∘

∴∠BCD=70
