The angle of elavation would be 45°, this is because straight up would be represented by 180°, and 90°, would remain as 1200 ft traveled, and half of 90°, is 45° which would double the distance traveled
Answer:

Step-by-step explanation:
From the question we are told that
The vector given is

Also 
Generally

Here
is the magnitude of a which is mathematically represented as

=> 
b is vector which we will assume to have the following parameters

So

=> 
=> 
Hence the vector be can be mathematically represented as

This means that the vector b is more than one value since it is made up of variable
This means that if

Then

7b^3/a^5
the negative needs to be brought to the bottom
The last one since you should first find the area of the square and then the triangle and last you add them and you will find the answer
Hi!
First, you have to add the addition equation.
(4 + 12) = 4 + 12 = 16
Now, the equation will look like this:
2.3 x 16
Now, you just take this equation like normal:
2.3 x 16 = 36.8
