Answer:

Option D.

Step-by-step explanation:

The angles forming a straight angle are supplementary.

We have angles APC and DPB forming a straight angle with adjacent angle to both (either angle APD or CPB).

It means the correct choice is D.

Answer:

x <= -42.5

Step-by-step explanation:

65 - 2x >= 150

-2x >= 150 - 65

-2x >= 85

2x <= -85

x <= -85/2

x <= -42.5

Question:

aivan3 [116]

Answer:

part A) The scale factor of the sides (small to large) is 1/2

part B) Te ratio of the areas (small to large) is 1/4

part C) see the explanation

Step-by-step explanation:

Part A) Determine the scale factor of the sides (small to large).

we know that

The dilation is a non rigid transformation that produce similar figures

If two figures are similar, then the ratio of its corresponding sides is proportional

Let

z ----> the scale factor

$\frac{CB}{C'B'}=\frac{CD}{C'D'}=\frac{BD}{B'D'}$

The scale factor is equal to

$z=\frac{CB}{C'B'}$

substitute

$z=\frac{4}{8}$

simplify

$z=\frac{1}{2}$

Part B) What is the ratio of the areas (small to large)?

<em>Area of the small triangle</em>

$A=\frac{1}{2}(2)(4)=4\ units^2$

<em>Area of the large triangle</em>

$A=\frac{1}{2}(4)(8)=16\ units^2$

ratio of the areas (small to large)

$ratio=\frac{4}{16}=\frac{1}{4}$

Part C) Write a generalization about the ratio of the sides and the ratio of the areas of similar figures

In similar figures the ratio of its corresponding sides is proportional and this ratio is called the scale factor

In similar figures the ratio of its areas is equal to the scale factor squared

Please Help???!!! I'm a 7th grader and need help! will give 20 points!

Ganezh [65]

Answer:

3. d= 20mm

4. r= 8 in

5. d= 14 mi

6. r= 11 yd

Step-by-step explanation:

Radius is half of diameter.

Example:

What is the diameter of a circle with a radius of 4?

If r = 4, d = 8

Do radius times 2.

Example 2:

What is the radius of a circle with a diameter of 10?

D = 10, so r = 5

Do diameter divided by 2.
