Hello, So I cam across this question and im really confused on how to comeplete it. Please could someone help me?

89

Step-by-step explanation:

Using the rule for alternate angles, angle ACD is also 39 degrees.

After finding this, we now have the 2 angles in the triangle: 50 and 39 .

Using this we can calculate the value of the angle adjacent to x: 180 - (50+39) = 91.

X and the adjacent angle are on a straight line so they add up to 180.

so, x = 180 - 91 = 89

Hope this helps.

Please mark brainiest.

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
