$\text{[math]}$

given the ratio between the angles of the TRIANGLE are 2 : 7 : 11

let the angles be 2x, 7x and 11x respectively.

we know that the SUM of angles of a triangle is 180°

therefore 2x + 7x + 11x = 180°

➡ 20X = 180°

➡ x = 180/20

➡ x = 9°

The angles are :-

2x = 2 × 9 = 18°
7x = 7 × 9 = 63°
11x = 11 × 9 = 99°

hence, correct option is (c) 18°, 63°, 99°
