Please help me due today i really need to pass

1) 45 degrees

2) 75 degrees

3) 37 degrees

4) 43 degrees

5) 137 degrees

Step-by-step explanation:

1) Angle 1 is equal to the 45 degree angle above it, so we know it is 45 degrees

2) All triangles are 180 degrees. Angle 2 = 180 - 60 - Angle 1 = 180 - 60 - 45 = 75

3) These three angles = 180 degrees. 180 - 68 - Angle 2 = 180 - 68 - 75 = 37

4) All triangles are 180 degrees. 180 - 100 - Angle 3 = 180 - 100 - 37 = 43

5) 180 - Angle 4 = 180 - 43 = 137

1.4

2.3

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
