Question

In the following diagram, $\angle ADB$ and $\angle BCA$ are in the major segment. So we can say that angle $ADB$ and angle $BCA$ are in the same segment. Find the angle $D$.

• A. $\angle D={50}^o$
• B. $\angle D={60}^o$
• C. $\angle D={70}^o$
• D. $\angle D={80}^o$

Answer 1

The correct option is C $\angle D={70}^o$

From the statement the diagram has same segment.
Angles in the same segment of a circle are equal.
So, angle $D$ $=$ angle $C$
$\angle D={70}^o$
