Question

answer this. ( both)
the one which is not clear is

In the given figure AB,CD. find the value of x
​

Answer 1

Answer:

x = 100°

Step-by-step explanation:

3. Join BD. Now BED is a triangle .

Angle ABD will be 90° as AB and BD are perpendicular to each other. So, angle EBD = 120°- 90° = 30°.

Angle BDE = 140°-90° = 50°.

Now in triangle BED ,

angle BDE + angle EBD + angle BED = 180°

50° + 30° + x = 180°

80° + x = 180°

x = 180° - 80°

x = 100°

Answer 2

Answer:

angle 1 = 50°

angle 6 = 130°

angle 2 = 130°

Step-by-step explanation:

angle 5 = 50°

therefore angle 1 = 50° (corresponding angles are equal)

now, angle 5 + angle 6 = 180 (supplemetary angles)

=> 50°+ angle 6 = 180°

=> angle 6 = 180°-50°

=> angle 6 = 130°

therefore, angle 2 = 130° (corresponding angles are equal)
