Answer:

Hey! Here is your answer!

Step-by-step explanation:

Given that AB∣∣CD

Taking BC as transversal,

∠ABC=∠BCD (alternate interior angles)

3x=105

x=35

Also, given that BC∣∣DE.

Taking CD as transversal,

∠CDE=∠BCD=105

(alternate interior angles)

Now applying angle sum property in triangle CDE,

∠CDE+∠DEC+∠DCE=180

105

+y+24

=180

y=51

solution
