What is the value of f

Mathematics
1 answer:
Vladimir79 [104]4 years ago
5 0

Answer:

f = 22

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

140° is an exterior angle of the triangle, thus

4f + 1 + 51 = 140, that is

4f + 52 = 140 ( subtract 52 from both sides )

4f = 88 ( divide both sides by 4 )

f = 22

Sveta_85 [38]

Answer:

  • 83 1/3 ft wide
  • 171 2/3 ft long

Step-by-step explanation:

Let w represent the width of the area. Then 2w+5 represents the length. The perimeter is twice the sum of length and width:

  P = 2(L+W)

  510 = 2(2w+5 +w) . . substitute given values

  255 = 3w +5 . . . . . . divide by 2

  250 = 3w . . . . . . . . . subtract 5

  83 1/3 = w . . . . . . . . .divide by 3; the width of the area

  2w+5 = 171 2/3 . . . .  the length of the area

The fenced area is 83 1/3 ft wide and 171 2/3 ft long.
