Answer:

8° = y

12° = x

________________

11° = z

7° = y

23 = x

Step-by-step explanation:

<u>What</u><u> </u><u>you</u><u> </u><u>need</u><u> </u><u>to know</u>

- m∠K ≅ m∠W; KB = WM

- m∠G ≅ m∠T; KG = WT

- m∠B ≅ m∠M; GB = TM

45° = [4x - 3]°

+ 3° + 3°

____________

\frac{48°}{4°} = \frac{[4x]°}{4°} \\ \\ 12° = x

Then use the Triangular Interior Angles Theorem to find the m∠Mthen set that equal to the m∠B:

180° = 41° + 45° + m∠M

180° = 86° + m∠M

- 86° - 86°

______________

94° = m∠M

94° = [11y + 6]°

- 6° - 6°

__________

\frac{88°}{11°} = {[11y]°}{11°} \\ \\ 8° = y

_______________________________________________

<u>What</u><u> </u><u>you</u><u> </u><u>need</u><u> </u><u>to know</u>

- m∠H ≅ m∠S; HC = SP

- m∠F ≅ m∠R; CS = RP

- m∠C ≅ m∠P; HF = SR

90° = [13y - 1]°

+ 1° + 1°

______________

\frac{91°}{13°} = \frac{[13y]°}{13°} \\ \\ 7° = y \\ \\ 90° = m∠R

Then use the Triangular Interior Angles Theorem to find the m∠Sthen set that equal to the m∠H:

180° = 28° + 90° + m∠S

180° = 118° + m∠S

- 118° - 118°

______________

62° = m∠S

62° = [6z - 4]°

+ 4° + 4°

____________

\frac{66°}{6°} = \frac{[6z]°}{6°} \\ \\ 11° = z

You clean a community park for 6.5 hours. You earn $42.25. How much do you earn per hour?
padilas [110]
6.5 hours is equal to:

60 mins x 6 + 30 mins = 390 mins

------------

42.25 / 390 = 13/120

------------

Now there are 60 minutes in an hour, so what we do is multiply 13/120 by 60 to find out how much you earn per hour...

13/120 x 60 = 6.5

--------------

You earn $6.50 per hour.

<h3>1.Area of the parallelogram= 288 square units</h3><h3>2.Area of the parallelogram=45 m^2</h3><h3>3.Area of the trapezoid   = 34 square in.</h3><h3>4.Area of the trapezoid = 8 square ft</h3><h3>5.Area of the rhombus= 27 square cm</h3><h3>6.Area of the rhombus= 108 square in</h3><h3>7.The area of the desktop is  = 1200 square in</h3><h3>8.The area of the rhombus is =84 cm^2</h3><h3>9.Area of the trapezoid  = 240 square ft</h3>

Step-by-step explanation:

1.

Base =16 ft and Height = 18 ft

Area of the parallelogram = base × height

                                       =16× 18 square units

                                       = 288 square units

2.

Base = 9 m and height = 5 m

Area of the parallelogram = base × height

                                        =(9×5) m^2

                                         =45 m^2

3 .

Height = 4 in and parallel sides are 12 in and 5 in

Area of the  trapezoid =\frac {1}{2} \times( {\textrm{sum of the parallel sides}}) \times height

                            =\frac{1}{2} \times (12+5) \times 4 square in.

                             = 34 square in.

4.

Height = 2 ft  and parallel sides are 2 ft and 6 ft

Area of the trapezoid =\frac {1}{2} \times( {\textrm{sum of the parallel sides}}) \times height

                              =\frac{1}{2} \times (2+6) \times 2 square ft

                              = 8 square ft

5.

Diagonals are 6 cm and 9 cm.

Area of the rhombus = \frac{1}{2}\times {\textrm{product of diagonals}

                               =\frac{1}{2 } \times 6\times 9 square cm

                               = 27 square cm

6. Diagonals are 12 in and 18 in

Area of the rhombus = \frac{1}{2}\times {\textrm{product of diagonals}

                               =\frac{1}{2 } \times 12\times 18 square in

                               = 108 square in

7. Given a desktop in the shape of a parallelogram has a base 30 in. and a height of 40 in

The area of the desktop is = (30 × 40 ) square in

                                            = 1200 square in

8. Given , a rhombus has one diagonal that is 14 cm and other diagonal 12 cm.

The area of the rhombus = \frac {1}{2} \times 14 \times 12 cm^2

                                         =84 cm^2

9.Given , the base of trapezoid are 24 ft  and 16 ft and height is 12 ft

Area of the trapezoid =\frac {1}{2} \times( {\textrm{sum of the parallel sides}}) \times height

                                    = \frac{1}{2} \times (24+16) \times 12 square ft

                                     = 240 square ft
