Answer:
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.
