of each angle.

Answer 1

Answer:

30°,45°,105°

Step-by-step explanation:

Ratio of angles=3:2:7

So,

3x+2x+7x=180°

=>12x=180°

=>x=180/12

=>x=15°

Then,

2x=2×15=30°

Similarly, measures of all angles are 30°,45° and 105°

Answer 2

Answer:

The angles are in the ratio 3 : 2 : 7

Let the angles be 3x , 2x and 7x.

Sum of all angles in a triangle is 180°

3x + 2x + 7x = 180°

12x = 180°

x = 15°

The angles are 3x , 2x and 7x

= 3(15), 2(15) and 7(15)

= 45° , 30° and 105°
