The angles of a triangle are in ratio 2:7:11. The angles area)(200,700...
Given, the ratio of angles of a triangle is 2:7:11.

Let the angles be 2x, 7x, and 11x.

Sum of angles of a triangle = 180°

Therefore, 2x + 7x + 11x = 180

Solving for x, we get x = 10.

Hence, the angles are 20°, 70°, and 110°.

Therefore, option C is correct, which gives the angles as 180°, 630°, and 990°.
