Question

Find x value and it's angle with full steps.​

Answer 1

Answer:

3x + 20= 5x -12

3x - 5x = -12 -20

-2x = -32

x= -32/-2

x= 16

Answer 2

Answer:

Given :

AD = 5x - 12

BC = 3x + 20

We know that the opposite sides of a parallelogram are equal. So,

3x + 20 = 5x - 12

=> 5x - 3x = 12 + 20

=> 2x = 32

=> x = 32 / 2

=> x = 16 cm

Side AD = 5x - 12 = 5 × (16) - 12 = 80 - 12 = 68 cm

Side BC = 3x + 20 = 3 × (16) + 20 = 48 + 20 = 68 cm

Therefore,

AD = 68 cm

BC = 68 cm

Hope it helped you..
