Find the area of a parallelogram with sides of 12 inches and 8 inches if one of the angles is 1200
48 sq. in
48v3 sq. in
96

 48√3 sq in

Step-by-step explanation:

The area is given by the formula ...

  A = ab·sin(α)

where a and b are the side lengths, and α is the angle between them.

Here, the given values show the area to be ...

  A = (12 in)(8 in)sin(120°) = (96 in²)(√3)/2

  A = 48√3 in²

The area of the parallelogram is 48√3 in².

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

x-3y=4
