Question

if the angle of a triangle are in the ratio 1:2:3 then the smallest angle in radian is​

Answer 1

Answer:

Sum of angles of triangle is 360 degree

Let 1x, 2x, 3x, are the angle of the triangle

Then,

1x + 2x + 3x = 360

6x = 360

X = 360/6

X = 60

Putting the value of x

1x = 60

2x = 2 x 60

= 120

3x = 3 x 60

= 180

The smallest angle is 60degree
