Describe how the value of the independent variable is related to the value of the dependent variable. ls the relationship additive or multiplicative?

The independent variable effects the dependent variable.

Step-by-step explanation:

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

66.666666667%

step-by-step explanation:

divide 150 by 100

divide 100 by 1.5

there you go!
