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.
