Answer:
The length of x in #1 is 15.57
Step-by-step explanation:
Let's use #1 as an example to teach show you how to do this. In a right triangle we can solve these using trig. In this particular one, we have the measure adjacent to the angle and we are looking for the one opposite of the angle. So we look at all the trig functions and select the one that uses both of those two terms.
Sinα = Opp/Hyp
Tanα = Opp/Adj
Cosα = Adj/Hyp
As you can see, Tan is the function we are looking for. So we plug in all known information into that equation.
Tanα = Opp/Adj -----> Plug in known values
Tan(60) = x/9 ----->Calculate out the trig function
1.73 = x/9 -----> Multiply by the denominator to solve
15.57 = x

Slope = (change in y)/(change in x)
.. = (-14 -0)/(2 -0)
.. = -14/2
slope = -7
In the first part, there are 10 fish total. 6/10 = 3/5 which means that there were 3/5 goldfish. When she buys two more, the total becomes 12 and 4/12 = 1/3 Hope this helps!
Answer:
Choice A.
Step-by-step explanation:
tan < ABC = 60/40
So m < ABC = 56.31 degrees.
This makes m < DBC = 56.31 / 2 = 28.15 degrees
tan 28.15 = DC / 40
DC = 40 tan 28.15
= 21.407 ft.
