R. D. Sharma Solutions for Chapter: Lines and Angles, Exercise 1: EXERCISE

How many pairs of adjacent angles are formed when two lines intersect in a point?

How many pairs of adjacent angles are there in the figure below?

In the figure, determine the numerical value of $x$.

In Figure, $AOC$ is a line, find $x$.

In Figure, $POS$ is a line, find $x$.

In Figure, lines $l_1$ and $l_2$ intersect at $O$, forming angles as shown in the figure. If $x=45°$, find the values of $y$, $z$ and $u$.

In Figure, three coplanar lines intersect at a point $O$, forming angles as shown in the figure. Find the values of $x$, $y$, $z$ and $u$.

In Figure, find the values of $x$, $y$ and $z$.
