Answer:
x=11
Step-by-step 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 :)
