Answer:
Length of the tunnel is 51.7 meters
Step-by-step explanation:
We are given that,
The surveyor is located 54 meters from one entrance at an angle of 56°.
The surveyor is located 31 meters from one entrance at an angle of 13°.
Let the length of the tunnel = x meters
So, using the law of cosines, we get,

i.e. 
i.e. 
i.e. 
i.e. x = 51.7 meters
Hence, the length of the tunnel is 51.7 meters

Answer:
C. 
Step-by-step explanation:
So we know that a vertical line is represented by
so we can already rule out two of the options. We also know that since the line runs vertically, all points will start with the same
coordinate. This means that the correct answer is 
The sum would be written as:

It goes from n=1 to =5 because it is the first 5 terms of the sum.
The sequence has a first term, a₁, of 1. The common difference, d, is 3. The explicit formula would then be:

Using the distributive property to simplify, we would have:
