Answer:

A

Step-by-step explanation:

I snipped the picture off the screen, copied it as a JPEG on my computer desktop, and then opened it in a picture editor.

In the picture editor, I rotated the picture 120 degrees counterclockwise.

A and C are similar, but C does not pivot around point V

I am including a picture of the quadrilateral rotated 120 degrees counterclockwise.

Answer:

   70.3 ft

Step-by-step explanation:

The ratio of the adjacent side (33 or KM) to the hypotenuse (X or KL) is the cosine of the angle:

  cos(62°) = 33/KL

Multiplying by KL/cos(62°) gives ...

  KL = 33/cos(62°) ≈ 33/0.4694 ≈ 70.292 ≈ 70.3

The length of KL is about 70.3 feet.

___

Make sure your calculator is in degrees mode.

3. Show that the expression 3b - 4 + 6(b-9) is equivalent to the expression 9 (b-6) -4. Show your work. ANSWER ASAP PLZZ
sattari [20]

EDITED:

so lets make the question more clear

lets make it like this, if were gonna make 10 = b vv (sorry I meant to say 10, but I said 6 ;-;

3(10) - 4 + 6(10-9) = 30 - 4 + 6 = 26 + 6 = 32

= THIS EQUALS 32

Now lets do 9(b-6) - 4 which will be turned into 9(10-6) - 4 = 36 - 4                          = THIS EQUALS 32

MY ANSWER IS YES (DONT ASK ME WHY IM WRITING IN CAPS (((: )

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

Answer:  tan(V)=2.92

Step-by-step explanation:

For this exercise you need to remember the following Trigonometric Identity:

tan\alpha =\frac{opposite}{adjacent}

You must observe the figure given in the exercise.

You can notice that the given triangle UVW is a Right triangle (because it has an angle that measures 90 degrees).

So, you can identify in the figure that:

\alpha =V\\\\opposite=UW=35\\\\adjacent=VW=12

Knowing these values, you can substitute them into  tan\alpha =\frac{opposite}{adjacent}:

tan(V)=\frac{35}{12}

Now you must evaluate:

tan(V)=2.916

Finally, rounding to the nearest hundreth, you get:

tan(V)=2.92
