Question

4) If x : y = 3:7, then fing the value of xyl
and
w
z ​

Answer 1

Answer:

x=54,y=126,w=126,z=54

Step-by-step explanation:

x+y=180(supplementary)

they are in ratio 3:7 so take

3a + 7a= 180

a=18

x=3a=54

y=7a=126

w=y=126(vertically opposite)

x=z=54(vertically opposite)

Answer 2

Answer:

Step-by-step explanation:

Given x:y = 3:7

x and y lie on same line therefore x+y=180⁰

3a + 7a =180⁰

10a =180⁰

a=18⁰

y=w { vertically opp

x=z angle}

x=3×a =3×18=54

y=7×a =7×18=126

z=54

w=126
