Question

help to find this solution ​

Answer 1

Answer:

75=angleBCD because these are alternate angles

75-30=45=angle ECD

30+45+angle DCG (G IS DRAWN BY CONSTRUCTION)

75+ANGLE DCG =180

ANGLE DCG=105

105 +30=x (these are alternate angles)

135 =x

Answer 2

Answer:

135 is correct option

Step-by-step explanation:

given,

AB is parallel to CD

EF is parallel to CD

Now,

angle B = angle C

therefore, 75°-30°= y°

45 = y°

according to question

angle GCE = angle FEC. (draw a line gd and hf )

angle GEC = 180°-75°+30°=135°

therefore, x=135°
