Since, DE∥BC and AB is a transversal, then∠DAB = ∠ABC Alternate interior angles⇒3x + 40 = x - 60⇒3x - x = -60 - 40⇒2x = -100⇒x = -50; not possibleSince, DE∥BC and ACis a transversal, then∠EAC= ∠ACM Alternate interior angles⇒2y+25 = y+20⇒2y-y = 20-25⇒y = -5; not possibleKindly recheck your question. Kindly ask the remaining queries in different threads. 0 View Full Answer Punyak answered this try by your own -1 Juhi Sharma answered this Hi Punyak, I tried it was not able to solve these questipns pf my book.
