I need help figuring this out. also please explain. I feel like I'm close to it, but I just don't know.

Step-by-step explanation:

Total angle sum of traingle = 180

In that triangle we have a right angle (90), and a 48 degree angle, and a y.

Add -->

90 + 48 + y = 180

y = 42

  y = 42°

Step-by-step explanation:

The triangle in which the acute angles are y and 48° is a right triangle, so y is the complement of 48°:

  y = 90° -48°

  y = 42°

__

The angles x and 48° together form a straight angle, so ...

  2x +48° = 180°

  x +24° = 90° . . . . . divide by 2

  x = 90° -24° = 66°

And z is the complement of x, so ...

  z = 24°

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

true !
