Question

ABCD is a parallelogram B=120 and D=x find x

Answer 1

Answer:

hey mate here is your answer thank you

Step-by-step explanation:

= Angle A= Angle C= 120° (Opposite angles of parallelogram are equal)

= Angle B= Angle D (Opposite angles of parallelogram are equal)

= Angle A+ Angle B+ Angle C+ Angle D= 360°

= Angle A+ Angle B+ Angle A+ Angle B= 360°

= 120° + 120° + 2(Angle B) = 360°

= (Angle B)= 360°- 240°

= Angle B= 120/2

= Angle B= 60°

= And Hence,

= Angle C= Angle B= 60°

or one more answer

= Angle a is 120 degree

= Angle C is also 120 degree(opp. sides)

= Angle b=angle d=180-120=60degree(as coi terroir angles are supplementary)

(note; I have given 2 answer of this question both are correct)

thank you
