Question

The angles of triangle are in the ratio of 2:7:11. The angles are... ​

Answer 1

Answer:

Angles are 18°,63°,99°

Step-by-step explanation:

let their common factor be x

therefore by angle sum property of triangle

2x+7x+11x=180°

20x=180

x=9

therefore 2x= 18

7x=63

11x=99

thanks

Answer 2

As we know that : Sum of all angles of the triangle = 180°

Let, the Angle if triangle be 2x, 7x and 11x

According to the question :

2x+7x+11x = 180

=> 20x = 180

=> x = 9

Angles are : 2×9 = 18°, 7×9 = 63° and 11×9 = 99°
