Mathematics

In the given figure AOB is a straight line. $\angle\, AOC\, =\, 3x,\, \angle\,BOC\, =\, 2x$. The value of x is

$36^\circ$

SOLUTION

$\because$ AOB is a straight line, $\angle\, AOC\, =\, 180^\circ$

$\therefore\, 3x\, +\, 2x\, =\, 180^\circ$

$\Rightarrow\, 5x\, =\, 180^\circ$

$\Rightarrow\, x\, =\, 36^\circ$

You're just one step away
