Answer:

x=11

Explanation:

First, we know that "supplementary" angles add up to 180 degrees. With this in mind, we can plug the values from your model into an equation:

(7x+33)+70=180

To solve this, first drop the parentheses because nothing is being distributed to the values inside them:

7x+33+70=180

Now we combine like terms, adding the 33 and the 70.

7x+103=180

Let's get rid of the 103 by subtracting it from both sides:

7x=77

Now we divide both sides by 7:

x=11

HTH :)
