Answer:
C. 
Step-by-step explanation:
Angle 6 and angle with measure 45° are vertical angles (opposite angles whan two lines intersect). By Vertical Angles Theorem, vertical angles are congruent, so
Angle 6 and angle with measure 
are the same side interior angles when two parallel lines are cut by transversal. The same side interior angles add up to 180°, then
A4 means the 4th number
so it is 17
It should be,
4x-8=2x-10 because you substitute that for y.
Now you do,
4x-2x because you do the opposite of the positive 2x as you bring it to the other side.
That is,
2x-8=10 now you bring the 8 to the other side.
2x=10+8 I added it because I do the opposite and it is a negative 8 so I add.
2x+18 now divide
x=9 that's the answer.
Answer:first one
hope this helps
4232 divided by 18 equals 235.1
