Question

ABCD is cyclic. if angle B =110 °, then find measure of angle d ​

Answer 1

Answer:

70 degree

Step-by-step explanation:

110+x=180

x=180-110

x=70

Answer 2

Answer:

Given □ABCD is cyclic and ∠B=110

∘

In a cyclic quadrilateral the sum of opposite angles=180

∘

⇒∠A+∠C=180

∘

⇒∠B+∠D=180

∘

⇒110

∘

+∠D=180

∘

⇒∠D=180

∘

−110

∘

⇒∠D=70
