Question

If the angles of a triangle are $x^{\circ }$, $2x^{\circ }$​ and $3x^{\circ }$, then the value of x is __ (in degrees).

Answer 1

We know that sum of the three angles of a triangle$={180}^{\circ }$​

Therefore, $x+2x+3x={180}^{\circ }$​

$or,6x={180}^{\circ }$,
$x=\frac{180}{6}={30}^{\circ }$
