Question

can you know answer please tell me​

Answer 1

Answer

18degree,72degree,90degree

explanation

let common ratio be x

so x +4x+5x=180( angle sum property of triangle)

10x=180

x=18

So angles =18degree,72degree,90degree

I hope it helps,please thanks follow and mark as brainliest

Answer 2

As we know that the sum of all angles of triangle ️ is 180°.

Let one angle be x

Then, other angles are 4x and 5x.

A/q,

=>x+4x+5x=180°

=>10x=180°

=>x=180°/10

=>x=18°

From this we can find all the angles of triangle,i.e.

x=18°

4x=72°

5x=90°
