Find The Perimeter. Simplify Your Answer.

Answers

Answer 1

Answer:

5c^2+2cd-2d^2-15

Step-by-step explanation:

Hello, to find the perimeter of any shape, you just add all the side together. In this picture, you would add all the sides up like this:

4c^2+4cd+12+-5d^2-5cd+2+c^2-d^2+1+3cd+4d^2-30

Then, combine like terms (add all of the numbers with the certain variable together) and you would get the answer which is:

5c^2+2cd-2d^2-15

Answers

Answer:

m<3 = 97

m<10 = 97

m<9 = 83

m<5 = 97

m<7 = 83

m<16 = 97

Step-by-step explanation:

m<3 = m<2 because of vertical angles

m<10 = m<2 because of corresponding angles

m<9 + 97 = 180

m<9 = 83

m<5 + 83 = 180

m<5 = 97

m<7 = m<6 because of vertical angles

m<16 = m<5 because of alternate exterior angles.

Solve for the area of the figure below and show work.

Answers

Answer and Step-by-step explanation:

1. We can see that this kite-shape has 4 triangles in it.

The area of a triangle is as follows:

[tex]A = \frac{bh}{2}[/tex]

Where:

b = Base (length)

h = Height

Top Right Triangle Area:

b = 9

h = 3

A = [tex]\frac{3 * 9}{2}[/tex]

A = [tex]\frac{27}{2}[/tex]

Bottom Right Triangle Area:

b = 9

h = 3

A = [tex]\frac{3 * 9}{2}[/tex]

A = [tex]\frac{27}{2}[/tex]

Top Left Triangle Area:

b = 4

h = 3

[tex]A = \frac{4*3}{2}[/tex]

A = [tex]\frac{12}{2}[/tex]

A = 6

Bottom Left Triangle Area:

b = 4

h = 3

[tex]A = \frac{4*3}{2}[/tex]

A = [tex]\frac{12}{2}[/tex]

A = 6

Now, we add all the areas together to get the area of the kite figure.

A = [tex]\frac{27}{2}[/tex] +

A = 27 + 12

A = 39

The area of the kite figure is 39 [tex]m^{2}[/tex].

2. We have to find the area of the trapezoid.

(I'm not sure if the 9 is for the entire bottom side length)

If the bottom side length is 9, then we would use the formula:

A = [tex]\frac{a + b}{2} h[/tex]

to find the area of the entire trapezoid.

A = [tex]\frac{2.4 + 9}{9}[/tex] × 8.2

A ≈ 46.74 [tex]mi^{2}[/tex]

Find JK................

Answers

Answer:

24 unit

Step-by-step explanation:

From the question,

JK = 2×NK.................... Equation 1

Using pythagoras theorem,

a² = b²+ c²................. Equation 2

From the diagram,

a = 15 unit, b = 9 unit, and c = NK

Substitute these values into equation 2

15² = 9²+(NK)²

Solve for NK

225 = 81+(NK)²

(NK)² = 225-81

(NK)²  = 144

NK = [tex]\sqrt{144}[/tex]

NK = 12 unit.

Substitute these value of NK into equation 1

JK = 2×12

JK = 24 Unit.
