The angle of a  triangle is in the ratio 2:4:3. What is the smallest angle of the triangle ?

                                                     

║⊕ANSWER⊕║

Angles of a triangle = 180°

GIVEN

Angles are in the ratio 2:4:3.

Let the angles be 2x, 4x and 3x

$2x+4x+3x=180\\9x=180\\x=20$

2x = 2 * 20

    = 40°

4x = 4 * 20

    = 80°

3x = 3 * 20

    = 60°

∴The SMALLEST ANGLE is 40°.
