X is equal 25 degrees. Line ac goes though the parallel lines. So bcd is x. Cdb is 180-50 equals 130. All angles add to 180. 180-130 equals 2X. So x equals 25.
Step-by-step explanation:
c=144°(vertically opposite angle)
b+c=180°(straight angle)
b+144=180
b=180-144
b=36°
The answer is c ................
