Hey. Let me help you on this one.
In order for us to solve this problem easier, let's break it apart. We can also graph the triangle so we get visual of this problem.
I drew a quick graph for you to easier understand this question. As you can see, Charlie is standing below the tree 45 feet from it, and we need to find the unknown angle measure.
Let's form a SOHCAHTOA function which you have probably already learned in your Geometry course.
First of all let's identify our sides. The side opposite of the right triangle is a Hypotenuse, and the side that's 45 feet is adjacent, since it's adjacent to the unknown angle.
We know that we need to use
(Cosine) with negative power to it in order to solve this question, since we are looking for the unknown angle measure.
Let's form the function which, Hypotenuse, and Adjacent side.
Now, let's solve the left part of this function
Awesome. You will need to use your calculator for this part. Find the value of 0.45 when negative Cosine is used on it.
Awesome. Let's round this number to the closest tenth
is the rounded value we have discussed below.
Answer: 63.3 degrees is the unknown measure of the angle

- Midpoint formula is
.
So starting with this one, we will be solving for the coordinates of the unknown endpoint separately. Starting with the x-coordinate, since we know that the midpoint x-coordinate is 5 and the x-coordinate of N is 2, our equation is set up as such: From here we can solve for the x-coordinate of Q.
Firstly, multiply both sides by 2:
Next, subtract both sides by 2 and your x-coordinate is
With finding the y-coordinate, it's a similar process as with the x-coordinate except that we are using the y-coordinates of the midpoint and endpoint N.
<u>Putting it together, the missing endpoint is (8,4).</u>
<em>(The process is pretty much the same with the other problems, so I'll go through them real quickly.)</em>
<h3>20.</h3><u>The missing endpoint is (7,2).</u>
<h3>21.</h3><u>The missing endpoint is (-5,1).</u>
