In a cyclic quadrilateral ABCD, ∠A is opposite to ∠C. If ∠A = 110 degree, then what is the value of ∠C?
Answer & explanation
Correct answer: option 3
Concept Used
In a cyclic quadrilateral, opposite angles are supplementary (i.e; they add up to \({180}^\circ\)).
Solution
\(\angle\)C = \({180}^\circ\) - \(\angle\)A
\(\angle\)C = \({180}^\circ\) - \({110}^\circ\) = \({70}^\circ\).
Therefore, \(\angle\)C is \({70}^\circ\).
