Question

ABCD is cyclic. if angle B =110 digri ,then find the measure of angle D.​

Answer 1

Answer:

∠D=70

Step-by-step explanation:

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  

Answer 2

Answer:

70°

Step-by-step explanation:

Let the angle be x.

As per question:

The opposite angles of a cyclic quadrilateral is supplementary.

∴ 110°+x=180°

x=180°-110°

x=70°
