Question

help me to do this sum!!!pls!!!I really need!!​

Answer 1

ANSWER : 110

Given, AB||CD

From E draw EF||AB||CD

EF||CD and CE is transversal

angle DCE + angle CEF = 180 (co - interior angles)

130 + angle CEF = 180

angle CEF = 50

Again, EF||AB and AE is transversal

angle BAE + angle AEF = 180 (co - interior angles)

x + angle AEC + angle CEF =180

Since angle AEF = angle AEC + angle CEF

x + 20 + 50 =180

x + 70 =180

x = 180 - 70

x = 110
