Question

in a traingle a,b and c are the angles of a traingle where a :b:c are in ratio 1:4:5find all the angles​

Answer 1

Answer:

let the required angles be 1x , 4x and 5x..

sum of all angles is 180°

1x+4x+5x=180°

10x =180°

x= 18 °

1x = 18

4x = 18×4 = 72

5x = 18×5= 90

hope it will help You ✌

Answer 2

Answer:

18, 72, 90

Step-by-step explanation:

let the ratio be 1 x,4x and 5x

1x+4x+5x=180. ( sum of all angles of triangle)

10x=180

x=180 /10=18

1* 18= 18

4*18=72

5*18=90

Rechecking answer

18+72+90= 180
