Question

Find the value of all the variables in the parallelogram shown in the picture. Give reasons for your answer​

Answer 1

Answer:

hello here we go

Step-by-step explanation:

(4x-12)⁰=120⁰ (opposite angles are equal)

(3x-y)⁰=60⁰ (opposite angles are equal)

so ,

angle DAB=60⁰

Angle ADC=120⁰.

REASON:

ABC+BCD+CDA+DAB=360⁰

120⁰+60⁰+120⁰+60⁰=360⁰

HOPE THIS WILL BE HELPFUL

Answer 2

Step-by-step explanation:

<D=<C (opposite angles of ||gram)

(4x-12) = 120°

4x = 120+12

4x = 132

x = 132/4

x = 33

<A=<C (opposite angles of ||gram)

3x-y = 60°

put,x=33

3×33-y = 60

99-y = 60

-y = 60-99

-y = -39

y = 39
