Answer 1

Answer:

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

3x+2x+7x = 180° (angle sum property)

12x = 180°

x = 180°/12

x = 15°

So, 3x=45°

2x=30°

7x=105°

Hope it helps

Thanks

Answer 2

Step-by-step explanation:

Given

The ratio = 3:2:7

let the angles be 3x,2x,7x

We know that the sum of angles of a triangle =180°

Then,

3x + 2x + 7x = 180

12x = 180

x = 180/12

x = 30/2

x = 15

The first angle = 3*15 = 45°

The second angle = 2*15 = 30°

The third angle = 7*15 = 105°.
