Step-by-step explanation:

Perimeter of the rectangle is the sum of all its four sides that can be find by:

$Perimeter=2(Length+Width)$

Length=2*Width

For, Perimeter=28.8 cm

$28=2(2*Width+Width)\\\\28=2*(2W+W)\\\\28=2(3W)\\\\3W=28/2\\\\3W=14\\\\W=14/3\\\\W=4.67 cm\\\\length=2*Width\\\\=4.67*2\\\\=9.34 cm\\\\$

$Length=9.34 cm\\\\Width=4.67 cm$

What is the value of x?

ziro4ka [17]

Answer:

x =12

Step-by-step explanation:

The exterior angle is equal to the sum of the opposite interior angles

30 + 4x+2 = 8+6x

Combine like terms

32 +4x = 8+6x

Subtract 4x from each side

32+4x-4x = 8+6x-4x

32 = 8+2x

subtract 8 from each side

32-8 = 8-8+2x

24 = 2x

Divide each side by 2

24/2 =2x/2

12 =x
