The folding chair has different settings that change the angles formed by its parts. Suppose Angle 2 is 26 and Angle 3 is 70. Find Angle 1. The diagram is not to scale.

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

graph of this function as shown below:

i think the correct option is the second option.

answer: it's d
