Question

In given figure, ABCD and ABEF are two cyclic quadrilaterals. If $\angle BCD={110}^0$, then $\angle BEF$ = ?

• A. ${55}^0$
• B. ${70}^0$
• C. ${90}^0$
• D. ${110}^0$

Answer 1

The correct option is D ${110}^0$

Given figure, ABCD and ABEF are two cyclic quadrilaterals.
Then AB||DC||EF
So $\angle BCD=\angle BEF={110}^0$ (Given $\angle BCD={110}^0$
