I think it would be A because that side looks double the size. Hope this helps!
The value of x would be 60 degrees
explanation
===============================
the triangle has one missing angle that would be congruent to x since they are corresponding angles which means they are congruent.
We know that the triangle has to add up to 180 degrees. We add the 2 angles and get 120 degrees. We subtract 120 degrees from 180 to find the 3rd missing angle that is congruent to x degrees. 180-120=60 degrees. If 60 degrees is corresponding to x degrees, therefore, x should be equal to 60 degrees.
Hope this helps :)
Answer:
========================================================
Explanation:
Let's solve for 'a' in the original equation. Each x shown below indicates multiplication.
I used the distributive property to factor out the 'a' in the second step.
As a check so far,
which shows we have the correct value for 'a'.
---------------
Once we determine the value of 'a', we can compute the expression your teacher wants.
