The second choice is correct. Given that angle 2 and angle 6 are congruent, the largest in each of the corresponding triangles are vertical angles meaning that two known angles are known in each triangle (and they are equal) which means that the last "unknown" (angles 3 and 7) are congruent. The lines DC and AB correspond with these defined, congruent triangles meaning they are parallel.
-32.48-(14.014)
- (32.48 + 14.014)
add 32.48 +14.014 by lining up the decimal
32.48
+ 14.014
------------
46.494
then bring back the negative
-(46.494)
Answer: -46.494
Hey there!☺



In our first step, we will simplify both sides of the equation:

Now subtract 4 from both sides:

In our last step, we will divide both sides by -2:

x=-7/2 is your answer.
Hope this helps!☺
