Question

In the figure, $\angle AOC$ and $\angle BO$ form a linear pair. If $a-b={80}^o$ then find the values of $a$ and $b$

Answer 1

To find : values of a and b

$a-b={80}^{\circ }$...(1)

$a+b=180$ [Linear pair]

Add both equations

$2a={260}^{\circ }$

$a={130}^{\circ }$

Put $a={130}^{\circ }$ in equation (1)

$b={50}^{\circ }$
