The marked angles are opposite angles, and as such they have the same measure. So, we have
Subtract 2a and 11 from both sides to get
Divide both sides by 4 to get
Now that we know the value of a, we can compute the measure of the angles. We can also verify that the solution we found is correct by verifying that both expressions actually give the same result:
Answer:
x = 4
Step-by-step explanation:
doesn't pass the vertical line test
Answer:
142
Step-by-step explanation:
Multiplying both sides by 5, you get:
x+18=160
Now, you can subtract 18 from both sides to get:
x=142
Hope this helps! Comment if this wasn't clear enough, or you need more explanation.
