  9 ft, 28 ft, 26 ft

Step-by-step explanation:

The perimeter is the sum of side lengths, so ...

  P = a + b + c

  63 = n +(4n -8) +(2n +8) . . . . fill in the given side lengths

  63 = 7n . . . . . . simplify

  9 = n . . . . . . . . divide by 7

  4n -8 = 36 -8 = 28 . . . . second side length

Solve for x in the diagram below.
larisa [96]

Answer:

x = 20

Step-by-step explanation:

The three angles form a straight line so they add to 180 degrees

x+ 100 +3x = 180

Combine like terms

100+4x= 180

Subtract 100 from each side

100+4x-100= 180-100

4x= 80

Divide each side by 4

4x/4 = 80/4

x = 20
