Pls say the answer.

First of all

EFGH is a parallelogram.

angle E + angle H =180 ° (being straight angle)

40°+x =180

x=180-40

x=140°

Again

angle E + angle F =180 (being straight angle)

or, Z + 70° =180

or,z=180-70

Z=110°

Now ,

Y= 70° (being alternate angle)

so , X=140° Y= 70° Z = 110 °

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
