Answer:  Choice B) SAS

=======================================================

Explanation:

The sides that have the double tickmarks are the same length. This forms one "S" of "SAS".

The square angles are 90 degree angles, or right angles. They are congruent. This forms the "A" of "SAS".

The overlapping sides are the same length, which forms the second "S" of "SAS".

The angle is between the two sides allowing us to use SAS. The order is important.

Find the distance between A and B. Round to the nearest hundredth. <br> ​A (-7,-1)<br> ​B (6,-5)
taurus [48]

Answer:

The distance between A and B is 13.6

Step-by-step explanation:

Distance formula=√(x2-x1)²+(y2-y1)²

Where

x1=-7

x2=6

y1=-1

y2=-5

Putting in the formula

Distance=√(6+7)²+(-5+1)²

D=√(13)²+(-4)²

D=√169+16

D=√185

D=13.6

The difference between the given values as a whole number is 27

<h3>Finding the difference between values</h3>

To find the difference between two numbers, subtract the number with the smallest value from the number with the largest value.

Given the following expression

44 - 17

This can also be expressed as

44 = 40 + 4

17 = 10 + 7

Substitute

44 - 17 = (40 + 4) - (10+ 7)

Expand

44 - 17 = 40 + 4 -10 - 7

44 - 17 = 40 - 10 + 4 - 7

44 - 17 = 30 - 3

44 - 17 = 27

Hence the difference between the given values as a whole number is 27
