Question

If the angle of a triangle are in the ratio 2:1:3, then find the measure smallest angle​

Answer 1

Sum of angles of a triangle is 180 degrees
So, we can write as,
2x + x + 3x = 180
6x = 180
x = 180/6
x = 30

The angles of the triangle are,
2(30) , 30 , 3(30)
60, 30, 90

Thus, the smallest angle of the triangle is 30 degree.

Answer 2

Answer:

Hello mate.

Here is your answer.

Let 'x' be used.

2x + 1x + 3x = 180( Sum of angles of triangle)

6x = 180

x = 180/6

x = 30

2x = 2×30=60

1x = 1×30=30

3x = 3×30=90

Therefore smallest angle = 30
