Question

In the given figure, $CE\perp AB,$ $\angle ACE={20}^{\circ }$ and $\angle ABD={50}^{\circ }$. Find $\angle BDA$ :

• A. ${50}^{\circ }$
• B. ${60}^{\circ }$
• C. ${70}^{\circ }$
• D. ${80}^{\circ }$

Answer 1

The correct option is B ${60}^{\circ }$

$\angle BAD={70}^{\circ }$
$\therefore \angle BDA={180}^{\circ }-({70}^{\circ }+{50}^{\circ })={60}^{\circ }$
