Question

If three angles of a triangle are in the ratio 1 : 2 : 6 ,find the greatest and smallest angles.​

Answer 1

Step-by-step explanation:

As the angles are in proportion 1:3:6

We can form the equation from condition ; Sum of all angles of a Triangle = 180

Therefore, x+3x+6x=180

10x=180

x=18

So the angles of given triangle comes out to be.

18, 54, 108 degree

so the Largest angle of the given triangle is = 108 degree
