Hello from MrBillDoesMath!

Answer:

BC = 3 * sin (66)/ sin(38)

Discussion:

From the law of sines:

sin(38) /3 = sin(66)/ BC

BC *  (  sin(38)/3 )  = sin(66)        => multiply both sides by BC

BC = sin(66) /  ( sin(38)/3)           => multiply both sides by ( 3/sin(38) )

BC = 3 * sin (66)/ sin(38)

which is the first choice.

Regards,  

MrB

notka56 [123]

Answer:

a) The variable, M represents the amount of fish Ms. Montesinos has

b) The set equation is 11 + 2 = 3 × M - 2

c) 5

Step-by-step explanation:

The given parameters are;

The number of fishes in Ms. Cruz's tank = 11 fishes

The number of fishes Ms, Cruz has after buying two more fishes = 3 × The amount of fish Ms. Montesinos has - 2 fishes

a) Let the variable, M represent the amount of fish Ms. Montesinos has

b) The set up equation is as follows;

11 + 2 = 3 × M - 2

c) From the equation, 11 + 2 = 3 × M - 2, we have;

13 = 3·M - 2

3·M = 13 + 2 = 15

3·M = 15

M = 15/3 = 5

M = 5

The number of fishes Ms. Montesinos has is 17 fishes
