Step-by-step explanation:

For SAS, you need two sides to be in proportion and the included angles to be congruent.

A) included angle between XY and YZ is Y, so wrong

B) included angle between UV and WV is V, so correct.

C) this ratio is just wrong.

D) included angle between XZ and ZY is Z, and the ratios check out, so correct.

If one pound of turkey costs 1.89 how many will x pounds cost

Mekhanik [1.2K]

Hello There!

It would be 1.89 times how ever many pounds there are:
But in this case we don't know the number of pounds so it would be:
1.89(x)

Hope This Helps You!
Good Luck :)

We can find the length of DE using the Pythagorean Theorem:

prohojiy [21]

What's the difference between A) and C)??
There should be an E) because the correct answer would be in either of these forms:
${DE}^{2} = {(4 - 1)}^{2} + {(1 - 3)}^{2} \: \: or \\ DE = \sqrt{( {3}^{2} + {2}^{2} )} \: \: or \\ {DE}^{2} = {(4 - 1)}^{2} + {(3 - 1)}^{2}$

PROBLEM: Riley has a rectangular shaped patio that is 13 feet long by 15 feet wide. He wants to DOUBLE THE AREA of the patio by

photoshop1234 [79]

Answer:

1) The equation that represents the total area of Riley's proposed ratio is $A' = (\sqrt{2}\cdot x)\cdot (\sqrt{2}\cdot y)$ .

2) The length and width of the new patio are approximately 18.4 feet and 21.2 feet, respectively.

Step-by-step explanation:

1) From Geometry we remember that area formula for the rectangle is represented by:

$A = x\cdot y$ (1)

Where:

$A$ - Area, measured in square feet.

$x$ - Length, measured in feet.

$y$ - Width, measured in feet.

From statement we know that Riley wants to double the area, that is:

$A' = 2\cdot A$ (2)

By applying (1) in (2), we get the following expression:

$A' = 2\cdot x\cdot y$ (3)

Given that Riley wants to double the area of the pation by increasing the length and width by the same amount, we can rearrange (3) by algebraic means:

$A' = \sqrt{2}\cdot \sqrt{2}\cdot x\cdot y$
