Question

Find the value of $\angle BEC$.

• A. 20°
• B. 30°
• C. 40°
• D. 50°

Answer 1

The correct option is B 30°


In the figure, AD is a straight line.
Hence, the given angles add upto 180°.

Then, $2x+x+3x=180°$
$\Rightarrow 6x=180°$
$\Rightarrow x=\frac{180°}{6}=30°$

Hence the value of $\angle BEC$= 30°.
