Explanation:

Question 11

We analyze each option:

• Option A: $\angle BAE$ is marked as $90^\circ$, not $25^\circ$.
• Option B: $\angle BAC$ is marked as $60^\circ$, not $25^\circ$.
• Option C: $\angle CAD$ is marked with a $25^\circ$ angle, so this matches.
• Option D: $\angle ADC$ is not an angle at vertex $A$ with the given diagram's context, and the diagram shows the $25^\circ$ at $A$ between $AD$ and $AC$.

To find $\angle EAD$, we can use the fact that the sum of angles around a point is $360^\circ$, but also, looking at the diagram, the angle marked as $150^\circ$ for $\angle EAD$? Wait, no, let's check the diagram. Wait, the diagram has $\angle EAD$ marked with a blue arc as $150^\circ$? Wait, no, let's re - examine. Wait, the angles around point $A$: we have $\angle EAC = 60^\circ$, $\angle CAB = 40^\circ$, $\angle BAD = 110^\circ$? Wait, no, the sum of angles around a point is $360^\circ$, but the diagram shows that $\angle EAD$ is marked as $150^\circ$ (the blue arc). Alternatively, we can calculate: the angle opposite or the given marked angle. Wait, the options include $150^\circ$ as option D. Looking at the diagram, the angle $\angle EAD$ is marked with a blue arc as $150^\circ$.

Answer:

C) CAD
