Question

The angles of a triangle are in the ratio $2:3:4$. Determine the three angles. What type of triangle is it?

Answer 1

Angle of triangle are in ratio

2:3:4

Let angle of triangle are 2x,3x,&

4x then

2x+3x+4x=${180}^{\circ }$ [angle sum property]

9x=${180}^{\circ }$

$[x={20}^{\circ }]$

then angle od trianle are =2x=${40}^{\circ }$

$=3x={60}^{\circ }$

$=4x={80}^{\circ }$

This triangle is angled triangles.
