Please help me find out what x=

47 degrees

Step-by-step explanation:

The angle you are looking at is vertical. Vertical angles look like an x, don't mind the random line. All of the angles on a vertical angle are equal to it's opposite. For example, since the angle is 133 degrees, the angle across from it is also 133 degrees. Since all of them need to add up to 360 degrees, subtract 266 (both 133 degrees) from 360. Which will be 92. 92 is the combination of both of the other angles, so divide that by 2, and there's X

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

2x^2+5x+17

your welcome. : )
