Answer:

22(c)

Step-by-step explanation:

Our current proportion is

15 miles

-------------

1 hour

We need feet per second.

Lets convert!

15 miles= 79200 feet(used googl to find this)

1 hour=3600 seconds(also used googl to find this)

( i know its not spelled that way brainly wont let me write the whole word out)

Now, our proportion is:

79200 feet

-----------------

3600 seconds

HOWEVER, this can be simplified!!!!

79200/3600=22

Final answer: 22, or C.

Hello from MrBillDoesMath!

Answer:

sin(A) =   k/c

sin(C) =   k/a

Discussion:

By definition of sine ,

sin(A) = side opposite angle / hypotenuse  =  k/c

sin(C) = side opposite angle/ hypotenuse =  k/a

Added remark:

From the first equation, k = c sin(A). From the second equation k = asin(C). Hence.

asin(C) = csin(A)                => divide both sides by "ac"

sin(C)/ c = sin(A)/a          

Which is the law of sines for a triangle.

Thank you,

MrB
