since,AB||ED and AE is the transversal
angel A + angel E =180°{sum of interior angles on the same side of transversal}
Given,
angle B= 142°,angle C=3x and angle D= 2x
we know that sum of angles in a Pentagon=540°
hence,angle A,+ angle B + angle C + angle D +
angle E = 450°
=>180°+142°+3x+2x= 540°
=>322°+ 5x= 540°
=>5x= 540°-322°=218°
=>x=218/5
=>x = 43.6°
it's wrong sorry
here's the right one
c= 181.something
d= 218.something
