Question

The angles of a triangle are in the ratio 1 : 2 : 3. Then the least angle is -------

Answer 1

Answer:1

Step-by-step explanation:

We know that the total angle measurement of a triangle is 180 degree therefore...we have to find what is 1,2 and 3's measurement...

let us take the number as x

means x+2x+3x=180

means 6x=180

x=180/6=30

means an x is 30 degree

therefore let us calculate the measurement of each angle...

1st angle is 1*30=30 degree

2nd angle is 2*30=60 degree

3rd angle is 3*30=90 degree

therefore angle 1 is the least

Answer 2

Hello .....

Here is your answer.....

Let angle 1 = x

Angle 2 = 2x

Angle 3 = 3x

In a triangle

Angle 1 + angle 2 + angle 3 = 180

X +2x + 3x = 180

6x = 180

x = 180/6

x = 30

Therefore....angle 1 = x = 30

Angle 2 = 2x = 2 ×30 =60

Angle 3 = 3x = 3×30 =90

HOPE THIS WILL HELP YOU !!!!!!!
