Question

In the figure, IF AB II CD, FIND X​

Answer 1

Answer:

x= 98

because, 40+52+x=180

therefore 40+52=92

180-92=98

Answer 2

Step-by-step explanation:

Given :

AB||CD

Angle BAD=52°

AngleECD=40°

To find :

Value of angle ECD(x)

Solution:

AB||CD......... (given)

Angle BAE=Angle EDC....... (alternate angles)

Angle ECD =40°

AngleEDC+ANGLE ECD+AngleDEC=180°....(sum

of all angles og triangle is 180°)

52+40+x=180°

92°+x=180°

x=180-92

x=88°
