Question

In the adjoining picture, find the value of $x$.

• A. $60$
• B. $300$
• C. $60$
• D. None of the above

Answer 1

The correct option is B $300$

The given picture is,
We can observe from the picture that,
On combining $x^o$ and ${60}^o$, a full angle (${360}^o$) is obtained.

$\therefore$ $x^o+{60}^o={360}^o$
Subtracting ${60}^o$ from both sides,
$\Rightarrow$ $x^o+{60}^o-{60}^o={360}^o-{60}^o$
$\Rightarrow$ $x^o={300}^o$

$\therefore$value of $x=300$

So, option(b.) is correct.
