Question

In the above figure, find the value of $x$, if the figure is a square.

• A. $30$
• B. $40$
• C. $50$
• D. $60$

Answer 1

The correct option is A $30$

We know each angle of a square measure $90$ degree.
On the line segment $l$ angle $x$ , point $P$ and $2x$ are forming angle on a straight line which is always $180$ degree
So as per the problem,
$\mathring{x}+\mathring{90}+2\mathring{x}=\mathring{180}$
$3\mathring{x}=\mathring{90}$
$\mathring{x}=\mathring{30}$
