Question

in each of the following figure ab is parallel to CD find the value of x in each case
please answer

Answer 1

1. x=140degree
2. x=100degree

Answer 2

Answer:

x=240°

Step-by-step explanation:

= Draw a line EF perpendicular to AB and CD passing through M.

In ∆BME

= angle BME + angle MBE + angle BEM= 180(angle sum property)

angle BME=35°+90°=180°

=angle BME=180°- 125°

=angle BME=45°

In ∆ DMF

angle DMF +angle MDF+ angle MED= 180°( angle sum property)

= angle DMF+75°+90°

= angle DMF= 180°- 165°

= angle DMF= 15°

= x = angle DMF+angle BME + angle EMF

=x= 15°+45°+180°

=x=240°
