Question

If angles of a triangle are in the ratio $2:3:4$. Find the value of each angle.

Answer 1

Let common ratio be $2x,3x$ and $4x$

$\to$ let common ratio be $x$

$\therefore$ Angle are $2x,3x$ and $4x$

$\therefore 2x+3x4x={180}^o$

$\therefore 9x={180}^o$

$\therefore x=\frac{{180}^o}{9}={20}^o$

$\therefore$ Angle are ${40}^o,{60}^o,{80}^o$
