Question

Need HELP ASAP!! please

Answer 1

B

b+1=2b
b = 1

3a-4=a+2
a=3

b = YZ

a = XY

Answer 2

• D. XY = 5 , YZ = 2

Step-by-step explanation :

As We Know that Opposite sides of the Parallelogram are equal.

SO,

(i) YZ = XW (opposite sides)

• YZ = 2b
• XW = b + 1

=> 2b = b + 1

=> 2b - b = 1

=> b = 1

Since, YZ = 2b

=> YZ = 2 × 1

=> YZ = 2.

Also,

(ii) XY = WZ (opposite sides)

• XY = 3a - 4
• WZ = a + 2

=> 3a - 4 = a + 2

=> 3a - a = 2 + 4

=> 2a = 6

=> a = 6/2

=> a = 3 .

Since, XY = 3a - 4

putting the value of a = 3.

=> 3(3) - 4

=> 9 - 4

=> 5

XY = 5.

Therefore, Option D is the required answer.
