Answer:

step by step below

Step-by-step explanation:

3. AB --> EF  (53°)

   BC --> DE  (37°)

   AC --> DF (90°)

4. EF/AB = 8/4 = 2 (scale factor)

5. DE = 2 x CB = 6

6. FD = √6²+8² = √100 = 10

How can you use the point-slope form of a line when only given two points?
pshichka [43]

Answer:

See below

Step-by-step explanation:

<u>Point -slope form is:</u>

  • y - y1 = m(x - x1)

By having one set of coordinates and knowing the value of the slope (m in the equation) you can use the form.

<u>How to find the slope?</u>

Here you need 2 points: Point 1 with coordinates x1, y1 and point 2 with the coordinates x2, y2

<u>Use the formula:</u>

  • m = (y2-y1)/(x2-x1)

<u>Example:</u>

  • m = -5, and one of the points has coordinates (9, 2) then point-slope form is:
  • y - 2 = -5(x - 9)

A vacant city lot is being turned into a neighborhood garden. the neighbors want to fence in a triangular section of the lot and
Alexxx [7]

Let x represent the length of the shortest side. Then the longest side is

... 2x -7 . . . . . . 7 ft shorter than twice the shortest side

and the 3rd side is

... x +2 . . . . . . 2 ft longer than the shortest side.

The perimeter is the sum of the side lengths,

... x + (2x -7) + (x +2) = 59 . . . . . the given perimeter length

... 4x -5 = 59 . . . . collect terms

... 4x = 64 . . . . . . add 5

... x = 16 . . . . . . . . divide by 4

Then the other sides are

... 2×16 - 7 = 25 . . . . . longest side

... 16 +2 = 18 . . . . . . . . third side

The side lengths are 16 ft, 18 ft, and 25 ft.

Alternate interior angles are:
(2x-70) = (x+30)
2x-x = 30+70
x = 100

the angle 5y is supplementary to the other angle.
5y + (100+30) = 180
5y + 130 = 180
5y = 180-130
5y = 50
y = 50/5
y = 10
