Given:
- The smallest angle of triangle = 1/6
To Find:
- The value of the largest angle of the triangle.
Solution:
The largest angle = x
The smallest angle = 6x
The other angle = 2x
The above values are given in the question.
Now using the sum of triangle rule we get,
⇒ x+6x+2x = 180 {adding the terms on RHS}
⇒ 9x = 180
⇒ x = 180/9 {dividing the terms}
⇒ x = 20
Now we get the largest angle as,
The largest angle = 6*20 = 120 {multiplying the terms}
∴ The value of the largest angle of the triangle = 120.
