Question

the angle of a triangle are in the ratio 2 is to 4 is to3 the smallest angle of the triangle is what please answer

Answer 1

let the angles be 2x , 4x , 3x respectively
we know that
sum of all angles of triangle is 180°
2x+4x+3x = 180°
9x = 180°
x = 180/9 => 20°

as we can see that , 2x is the smallest angle
so measure of smallest angle = 2×20° => 40° option (b) is correct
hope this helps

Answer 2

Given ratio of the angles of a triangle =2:4:3

We know that Sum of angles of a triangle is 180°

Now,

2x +4x + 3x = 180

9x =180

x =20°

So the angles are 40,60,80

The smallest angle is 40°
