# In the given figure, $\angle$POR and $\angle$QOR form a linear pair and $a-b=40^o$. Then the values of a, b respectively are __________.

##### ANSWER

$110^o, 70^o$

##### SOLUTION
$\angle POR$ $= b$ and $\angle QOR$ $= a$
$\because$ line PQ is a straight line
$\Rightarrow$ $\angle POQ$ $=$ $180^{\circ}$
$\Rightarrow$ $a+b$ $=180^{\circ}$ $....(1)$
$\because$  $a-b$ $=40^{\circ}$    $....(2)$
From equation (1) and (2)
$a$ $=110^{\circ}$ and $b$ $=70^{\circ}$
Hence the correct option is $(A)$  $110^{\circ}$$,70^{\circ}$
