Question

If y/x = 5 and z/x = 4 , then the value of x is

​

Answer 1

Answer:

18 degree

Step-by-step explanation:

y /x=5

this gives

y=5x eq 1

similarly , z =4x eq 2

now by linear pair axiom

x +y+z =180

4x +5x +x =180 fromm 1 and 2 equations

10x =180 x=18

Answer 2

Answer:

X= 18°

Step-by-step explanation:

Given,

y/x = 5 or, y= 5x

z/x= 4 or, z= 4x

Now,

x+y+z= 180° [ The three angles sum upto a straight line i.e., 180°]

or, x+5x+4x = 180°

or, 10x = 180°

or, x = 18°

Hence, the value of x is 180°
