Question

In the given figure AB parallel CD,then find the value of x..
Please tell me fast
​

Answer 1

Answer:

given

AB // CD

so, BAC=DCF=75

so, DCF+FCE=180(linear pair)

FCE=180-75=105

in triangle CEF

105+30+x=180

so, x=180-105-30=45

Answer 2

★ Answer :

In the given figure ,

AB || CD

therefore , 75° and y are linear pairs.

75 + y = 180°

y = 180 - 75

y = 105°

We know that ,

Vertically opposite angles are equal..

Angle ACD = Angle FCE

105° = Angle FCE

In ∆ FCE

Angle FCE + Angle FEC + Angle CFE = 180°

105 + x + 30 = 180

135 + x = 180

x = 180 - 135

→ x = 45°
