Answer: Choice A) x = 15; y = 17

---------------------

Explanation:

The "7x+7" angle and the "112 degree" angle are congruent. They are vertical angles. So
7x+7 = 112
7x+7-7 = 112-7
7x = 105
7x/7 = 105/7
x = 15

We technically have enough to stop here, but let's keep going to find y

The "4y" angle and the "112 degree" angle are supplementary. They form a single straight line. They add to 180 degrees

So,
4y+112 = 180
4y+112-112 = 180-112
4y = 68
4y/4 = 68/4
y = 17

Answer:

B. Point B is opposite of Point C

Step-by-step explanation:

Let B (x1, y1) and C (x2, y2) be two points.

if sum of B and C is 0:

([x1 + x2]/2, [y1 +y2]/2 ) = (0, 0)

then

[x1 + x2]/2=0 then x1+x2 = 0 then x1 = -x2

similarly, [y1+y2]/2 = 0 then y1+y2 = 0 then y1=-y2
