Question

In the figure above, two line segments meet at a point on line $l$. Find the value of $x$.

• A. $45$
• B. $60$
• C. $90$
• D. $15$

Answer 1

Answer: (A)

$45$

In the given figure, two line segments meet at a point on line $l$ such that they are making angle on a straight line.
We know angle formed on a straight is always supplementary i.e $180$ degree
As per problem,
$\mathring{x}+\mathring{x}+2\mathring{x}=\mathring{180}$
$4\mathring{x}=\mathring{180}$
$\mathring{x}=\mathring{45}$
