What is measurement of angle 2 and 11

Angle 2 = 40 degrees              Angle 11 = 60 degrees

Step-by-step explanation:

Start by using angle 1 to find angle 2

angle 1 is 140 + 2 is unknown = 180 degrees

140 + x = 180

-140        -140

x = 40

Angle 2 is 40 degrees

Now add together angles 2 and 9 to find the measure of angle 11

40 + 80 + x = 180

120 + x = 180

-120        -120

x = 60

Angle 11 is 60 degrees

Gerbils Diana has = z

Gerbils Jackie has = 4z = w

Hence, w = 4z

Independent Variable is a variable that stands alone and isn't changed by the other variables you are trying to measure.

Hence, the independent variable is z here.

Dependent Variable is something that depends on other factors. 

Hence, the dependent variable is w here.
