R. D. Sharma Solutions for Chapter: Lines and Angles, Exercise 2: EXERCISE

In Figure, if $l \left|\right| m$, $n \left|\right| p$ and $\angle 1 = 85°,$ find $\angle 2$.
   

In Figure, find out $\angle PXR$, if $PQ\parallel RS$.

In Figure, we have
   
$\angle MLY=2\angle LMQ,$ find $\angle LMQ$.

In Figure, we have

$\angle XLM = (2x - 10)°$ and $\angle LMQ= \left(x + 30\right)°$, find $x$.

In Figure, we have
  
$\angle XLM = \angle PML$, find $\angle ALY$.

In the figure,

$\angle ALY = (2x - 15)°, \angle LMQ = (x + 40)°,$ find $x$.

In the given figure, $PQ\parallel RS$. Find the value of $x$.

In Figure, the corresponding arms of $\angle ABC$ and $\angle DEF$ are parallel. If $\angle ABC = 75°$, find $\angle DEF$. (Write the answer without degree symbol)
