7. Find DE.<br> 11-25<br> E<br> А<br> 4x + 1<br> D<br> С
Arlecino [84]

Answer:

  • DE = 37

Step-by-step explanation:

AD = DC and BE=EC ⇒

DE = 1/2AB

  • 4x + 1 = 1/2(11x - 25)
  • 2(4x + 1) = 11x - 25
  • 8x + 2 = 11x - 25
  • 11x - 8x = 2 + 25
  • 3x = 27
  • x = 27/3
  • x = 9

DE = 4*9 + 1 = 36 + 1 = 37
