Question

Angles of a triangle are in the ratio $3:4:5$. Find the angles.

Answer 1

Angles are in the ratio of $3:4:5$
Let the angles be $3x,4x,5x$
$\therefore 3x+4x+5x=180$...........Sum of the angles of triangle are ${180}^o$
$\therefore 12x=180$
$\therefore x=15$
Hence, the angles are: ${45}^{\circ },{60}^{\circ },{75}^{\circ }$
