Question

the angle of a triangle are in the ratio 2:3:7 find the angal​

Answer 1

Answer:

let us take the sides 2x 3x 7x

since sum if all angles of a triangle is 180

ATQ

2x+3x+7x=180

12x=180

x=180/12

x=15

so the sides are 2x=2*15=30

3x=3*15=45

7x=7*15=105

Answer 2

ANSWER:-

Given:

The angle of a triangle are in the ratio 2:3:7.

To find:

Find the angle.

Solution:

We know that, sum of all sides of ∆=180° [property]

Let the angle be x.

➨2x + 3x + 7x = 180°

➨12x = 180°

➨ x= 180°/12

➨ x= 15°

Now,

1st angle, 2x = 2×15° =30°

2nd angle, 3x= 3×15°= 45°

3rd angle, 7x = 7×15°= 105°

Hope it helps ☺️
