angle 1= 55°
you can find this by doing 180-125=55
you get the 180 because angle 1 and 2 are on a straight line and there’s a line in between that creates the angles. a straight line is always 180°
anyways the answer is 55°

Which is a scaled copy of Polygon A?Identify a pair of corresponding sides and a pair of corresponding angles. Compare the areas of the scaled copies.

Answers

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete as the polygon A (and other possible polygons to select from) are not given. So, I will answer on a general term.

Assume that Polygon A is a rectangle of dimension 2ft by 5ft.

[tex]Length = 2ft[/tex]       [tex]Width = 5ft[/tex]

Possible scaled copies can be gotten by multiplying the dimension of A by the same scale factor.

Take for instance, the scale factor k is:

[tex]k = 3[/tex]

A scaled copy of polygon A (say polygon B) is: 6ft by 15ft

This is gotten by:

[tex]Length = 2ft * 3 = 6ft[/tex]     [tex]Width = 5ft * 3 = 15ft[/tex]

The area of A is:

[tex]Area = 2ft * 5ft = 10ft^2[/tex]

The area of B is:

[tex]Area = 6ft * 15ft = 90ft^2[/tex]

See attachment for polygons

Comparison

The area of B is greater than the area of B.

This method can be applied to scale factors

A museum groundskeeper is creating a semicircular statuary garden with a diameter of 31 feet. There will be a fence around the garden. The fencing costs $8.25 per linear foot. About how much will the fencing cost altogether?

Answers

Answer: $657.53

Step-by-step explanation:

Circumference of a circle = πd

But in this case, it's a semi circle, so the circumference will be:

= πd/2

= (3.142 × 31) / 2

= 97.402/2

= 48.701

Then, the total amount of the fencing will be:

= 48.701 + 31

= 79.701

Then, the fencing cost will be:

= 79.701 × $8.25

= $657.53

What is the equation of the directrix

Answers

Answer:

Step-by-step explanation:

y=-1

Can someone please help me with math

Answers

Answer:

3 - B

4 - D

Step-by-step explanation:

Hey There!

they are asking for the slope in slope intercept form

y = mx + b

where m = slope and b = y intercept

The slope is change in y over change in x

as y goes up 4 x goes up 2

4/2=2 so the slope (or m ) is 2

The y intercept is at point (0,-4)

So the y intercept (or b) is -4

now we add everything together and get that the equation of the line is

y=2x-4

for 4

the best rule is D 2n+2

Why? because the rate of change is 2

and the y intercept is at (0,2) so the best rule would be 2n+2
