Please help me i really need it geometry?

height= 30 area= 2160

Step-by-step explanation:

I don't think this is even right, but since a triangle adds up to 180, subtract the 72 and both 39's from 180. that should give you 30, the missing number (the height)

Then, to find area the formula is a=b*h

You already have the base in the image and you already calculated the height

Again, I don't know if this is right. It's not the same as how I do it here

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
