Question

The angle of triangle are $2x,3x$ and $5x$ and the angles

Answer 1

Given the angles of the Triangle are

$2x,3x,5x$

Hence, $2x+3x+5x={180}^o$ (Interior angle sum is ${180}^o$)

$\Rightarrow 10x={180}^o\Rightarrow x=\frac{{180}^o}{10}={18}^o$

So, the angles are

$2x=2\ast {18}^o={36}^{o}3x=3\ast {18}^o={54}^{o}5x=5\ast {18}^o={90}^o$
