I need help to solve please

6!

Step-by-step explanation:

I'm not as sure about this answer, but I got it like this!

We know that a triangle adds up to 180. Two of our given measurements are 90 and 63. Adding those together we get 153. To solve for x, you'd have to subtract that from 180.

From there, you get 27! That's the answer to the equation, but not the value of x.

4 time 6 ( which is x) is 24, plus 3 is 27, so we know that x is 6!

I hope this helped, and made sense!!

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
