Answer 1

Answer:

y/x=5

z/x=4

so y= 5x

x= 4x

ATQ

x+y+z=180

x+4x+5x=180

10x=180

x=180/10

x=18

Answer 2

1. given that y/x =5 then y=5x......….........(
2. $again \: \frac{z}{x} = 4 \: then \: z = 4x...(2)$
3. $we \: know \: that \: x + y + z = 180$

$x + 5x + 4x = 180$

$10x = 180$

$x = \frac{180}{10} = 18$
