Question

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

Answer 1

Answer:

let the three angles be 2x,7x,and 11x

according to question

2x+7x+11x=180 degree

20x=180

x=180/20

since, x=9

threrfore angles are:

2x=2×9=18 degree

7x= 7×9=63 degree

and 11x=11×9=99degree

Answer 2

Answer:

18°, 63° and 99°

Step-by-step explanation:

Let the angles are 2x, 7x and 11x

• 2x + 7x + 11x = 180° (Angle Sum Property Of Triangle)
• 20x=180°
• x=9°

Then, Angles Are:

1. 2x = 2 × 9 = 18°
2. 7x = 7 × 9 = 63°
3. 11x = 11 × 9 = 99°
