The angles of a triangle are in the ratios 2:3:4.Find them

Answer 1

★ Given :-

The angles of a triangle are in the ratios 2:3:4.Find them ?

★To find :-

Angles of traingle.

★ Solution :-

We know that,Sum of all angles Of traingle Is 180°

Let the angle be x.

→ 2x+3x+4x = 180°

→ 9x = 180°

→ x = 180/9

→ x = 20

Putting Value of X = 20

∠ 1 = 2x

= 2×20 = 40°

∠ 2 = 3x

= 3×20 = 60°

∠ 3 = 4x

= 4×20 = 80°

So, The Angles of Traingle Are 40°,60°and 80°.

Answer 2

Let the angles of a triangle be 2x, 3x & 4x:

Then,

The sum of all angles of a triangle=180°

(2x+3x+4x) =180°

9x =180°

x =180/9

x =20°

The angles of a triangle is 2x=(2×20)°=40°

3x=(3×20)°=60°

4x=(4×20)°=80°
