Question

if angle of triangle are in the ratio 2 : 3 : 4 find the value of each angle​

Answer 1

Let the respective angles = 2x°, 3x°,4x°.

We know, sum of angles of a triangle =180°.

By angle sum property of triangles,

(2+3+4)x°=180°

⇒9x=180

⇒x=180/9=20.

∴ 2x°=2(20)°=40°.

∴3x°=3(20)°=60°.

∴4x°=4(20)°=80°.
