Question

□ABCD is a cyclic quadrilateral, ˂A= 70˚. Find ˂BCD​

Answer 1

Answer:

<BCD=110⁰

Step-by-step explanation:

□ABCD is a cyclic quadrilateral,

˂A= 70˚

therefore opposite sides of cyclic quadrilateral is supplementary

<A+<BCD=180

70°+<BCD=180

<BCD=180-70

<BCD=110⁰

Answer 2

Answer:

˂BCD= 110°

Step-by-step explanation:

□ABCD is a cyclic quadrilateral

in a cyclic quadrilateral sum of opposite angles = 180°

˂A= 70˚

˂A + ˂BCD=180°

70° + ˂BCD= 180°

˂BCD= 180°-70°= 110°

˂BCD= 110°
