Answer 2

We know that all the angles in a triangle added up will be 180 degrees

ratio is 5:4:1

let x be a variable for the ratio,

5x+4x+x=180 degrees

10x=180

x = 18 degrees

so angles are

 5x=5*18= 90 degrees

 4x=4*18= 72 degrees

    x=18 degrees

                                               hence angles are

                                                   90 degrees,72 degrees and 18 degrees

                   it is also a right angled triangle as one of the angles is 90 .
