Answer 2

Answer:

let the angles be x , 4x , 5x ,.

Step-by-step explanation:

Therefore, we all know the angle sum property that sum of three

angles of a triangle is equal to 180 degree.

so, lets put the above thing in this sum

=>     x+4x+5x =180

=>     10x=180

=>      x=180/10

=>       x =18

therefore lets put he value of x

X=18

4X =72

5X= 90
