Answer:

c) BC/tan(20°)

Step-by-step explanation:

The mnemonic SOH CAH TOA can help you remember the relations between trig functions and angles. It tells you ...

Sin = Opposite/Hypotenuse

Cos = Adjacent/Hypotenuse

Tan = Opposite/Adjacent

In the case of the present triangle, these relations mean ...

sin(B) = AC/BC ⇒ AC = BCsin(70°)

cos(C) = AC/BC ⇒ AC = BCcos(20°)

tan(B) = AC/BA ⇒ AC = BAtan(70°)

tan(C) = BA/AC ⇒ AC = BA/tan(20°)

The answer choice that is not on this list is ...

c) BC/tan(20°) . . . . . . not equivalent to AC

Additional comment

The interior angle at C is the supplement of the given angle 160°. These angles form a linear pair.

C = 180° -160° = 20°

The interior angle at B is the complement of the interior angle at C.

B = 90° -20° = 70°

The approximate volume in milliliters, y, for a volume of x fluid ounces is equal to 29.57 times the value of x. Which table rep

Angelina_Jolie [31]

The table which represents the relationship is:

Fluid ounces, x Volume y ( in millimeters)

1 29.57

2 59.14

3 88.71

4 188.28

In mathematics, a relation describes how two distinct sets of information related to one another. If more than two non-empty sets are taken into consideration, a connection between their elements will indicate that more than two sets are being evaluated.

Let y be the volume of fluid x in millimeters.

Now, y is equal to 29.57 times the value of x.

Therefore,

y = 29.57 × x

y = 29.75x

So, when x = 1:

y = 29.75(1) = 29.57

When x = 2,

y = 29.57(2) = 59.14

When x = 3,

y = 29.57(3) = 88.71

When x = 4,

y = 29.57(4) = 118.28

Therefore, the table that represents the relationship is:

Fluid ounces, x Volume y ( in millimeters)

1 29.57

2 59.14

3 88.71

4 188.28

The grocery store is located at a point on a coordinate plane with the same y coordinate as the bank but with the opposite x coo

Cerrena [4.2K]

The vertical axis on a graph is the y-axis and the horizontal axis is the x-axis. Keeping this in mind, if they have the same y coordinate that means vertically they are on the same level but their x coordinates are opposite each other, this means 2 things:
1. they are not on the same level horizontally
2. you have to cross the vertical (y) axis to get from one point to the other.

So to answer your question, These two points are reflected across the y axis.

Hope this helps.
