Question

Angles of a triangle are in the ratio 2 : 4:3. The smallest angle of the triangle is
(a) 60
b) 40
(c) 20
(d) 80
​

Answer 1

Answer:

The smallest angle is 40°

Answer 2

Answer:

b) 40

Step-by-step explanation:

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

sum of all angles in a triangle = 180°

2x+3x+4x = 180°

9x = 180°

x=20°

The smallest angle is 2x = 2*20 = 40°.
