Find the value of x
Please answer the above question fast​

Answer 1

Answer:

140°

Step-by-step explanation:

angle ABC = angle BCD (alternate angles)

65=25+ angle ECD

angle ECD= 65-25=40°

angle CEF +angle ECD =180°

X+40=180

X= 180-40=140°

Answer 2

Given: CD || EF

∠ FEC + ∠ECD = 180°

[Sum of co-interior angles is supplementary to each other]

=> ∠ECD = 180° – x° = 50°

=> x=180°-50°=130°
