Question

In the adjoining figure ABCD is a parallelogram, then the measure of x is :​

Answer 1

Answer:

90

Step-by-step explanation:

angle FAB =60-30=30 DEGREES

angle ABC+angle BCD=180

(angle ABO+ angle OBC) + angle BCD= 180

angle ABO + 60 +60 =180

Angle ABO=60

now

in triangle AOB

Angle AOB+ AngleOAB + angle OBA = 180

ANGLE AOB + 30 +60=180

angle AOB =90

x=90. (vertically opposite angle

Answer 2

Answer:

90

Step-by-step explanation:

angle FAB =60-30=30 DEGREES

angle ABC + angle BCD=180

(angle ABO+ angle OBC) + angle BCD= 180

angle ABO + 60 +60 =180

Angle ABO=60

now

in triangle AOB

Angle AOB+ Angle OAB + angle OBA = 180

ANGLE AOB + 30 +60=180

angle AOB =90

x=90. (vertically opposite angle
