Answer:

Traversals, Eh?

2-99 degrees

3-81 degrees

4-81 degrees

Step-by-step explanation:

So to find the measures of these angles, we need to find the relationship between these angles.

1 and 2 are Alternate Exterior angles(Maybe, been a while since I have done traversals).

They are supplementary angles the sum of their measurements is 180

180=<1+<2

So, I'll spare the math and let you figure out how I got it.

<2=99 degrees

1 and 3 are vertical angles, meaning they have got the same angle measure.

So, <3 is 81 degrees

1 and 4 are Corresponding Angles, meaning they have the same angle measure.

So, <4 is 81 degrees

Hope This helps!

P.S. Google the Names of the angles, I might be wrong!

Answer:

2: 99° 3: 81° 4: 81°

Step-by-step explanation:

2 is supplementary to 1 so subtract 81 from 180 = 99.

3 is vertical angle with 1 so they are equal

4 is alternate interior angle with 3 so they are equal

hope this helps stay safe :)

PLEASE HELP ASAP !!

Answer:

First figure: $954cm^3$

Second figure: $1,508yd^3$

Third figure:

Height= q
Side length = r

Fourth figure:  $726cm^3$

Explanation:

A. First figure:

1. Formula:

$\text{Volume of a cylinder}=\pi \times radius^2\times length$

2. Data:

radius = 9cm / 2 = 4.5cm

length = 15 cm

3. Substitute in the formula and compute:

$Volume=\pi \times (4.5cm)^2\times (15cm)\approx 954cm^3\approx 954cm^3$

B. Second figure

1. Formula:

$\text{Volume of a leaned cylinder}=\pi \times radius^2\times height$

2. Data:

radius = 12yd

height = 40 yd

3. Substitute and compute:

$Volume=\pi \times (12yd)^2\times (40yd)\approx 1,507.96yd^3\approx 1,508yd^3$

C) Third figure

a) The height is the segment that goes vertically upward from the center of the base to the apex of the pyramid, i.e. q .

The apex is the point where the three leaned edges intersect each other.

b) The side length is the measure of the edge of the base, i.e. r .

When the base of the pyramid is a square the four edges of the base have the same side length.

D) Fourth figure

1. Formula

The volume of a square pyramide is one third the product of the area of the base (B) and the height H).

$Volume=(1/3)B\times H$

2. Data:

height: H = 18cm

side length of the base: 11 cm

3. Calculations

a) Calculate the area of the base.

The base is a square of side length equal to 11 cm:

$\text{Area of the base}=B=(11cm)^2=121cm^2$

b) Volume of the pyramid:

$Volume=(1/3)B\times H=(1/3)\times 121cm^2\times 18cm=726cm^3$

How much greater is the median number of pairs of shoes in the inventory at the Golf pro Shop than the median number of pairs of

lana66690 [7]

Answer: 20

To get this answer, you find the median of the golf pro shop data (a = 40) and the median of the tennis pro shop data (b = 20). Then you subtract to get a-b = 40-20 = 20. The median of any box plot is the vertical line inside the box plot.
