Answer:
the answer to the question is C
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
It is 1,000 bigger than the one in the tens place. 5,000 compared to 50
K here you go!!! So, this is the slope formula: m=(y_2-y_1)/(x_2-x_1). We can input the example coordinates given to create: (-4-3)/(-4-2). Then, I can simplify to make -7/-6 or 7/6. You can make it improper or not, up to you or the question. Also, in the part where I inputting the numbers into the formula, it doesn't matter what y-coordinate value or x-coordinate value you use. The slope won't change.

It would be 56 mph. you need to divide 224 from 4 to get the unit rate
