Question : $ABCD$ is a cyclic quadrilateral of which $AB$ is the diameter. Diagonals $AC$ and $BD$ intersect at $E$. If $\angle DBC=35^\circ$, then $\angle AED$ measures _________
Option 1: 35$^\circ$
Option 2: 45$^\circ$
Option 3: 55$^\circ$
Option 4: 90$^\circ$
Correct Answer: 55$^\circ$
Solution : Given, a cyclic quadrilateral $ABCD$ with $AB$ as a diameter And, $\angle DBC=35^\circ$ We know, $\angle ACB=90^\circ$ (angle in semicircle) In $\triangle BEC$, $\angle ECB+\angle EBC+\angle BEC=180^\circ$ or, $\angle BEC=180^\circ-90^\circ-35^\circ$ So, $\angle BEC=\angle AED = 55^\circ$ (vertically opposite angle) Hence, the correct answer is 55$^\circ$.
