Answer:
1129 + 99x
Step-by-step explanation:
Let us use x in this equation; x = amount of hours.
You are currently at 1,129 ft.; so lets start with that.
After then you don't know how many hours you climb but you know at what pace. So you use a variable to plug in with numbers later.
So your equation turns into;
1,129 + 99x
I would add 4+6+8 but to make this easier i would maybe split them

Hello!</h2>
The answer is: C. 16 m.
<h2>Why?</h2>
The figure is a right triangle, it means that we can solve it by using the Pythagorean theorem which states that, the largest side of a rectangle (hypotenuse) is equal to the sum of the other two side squares:

Where:
c=34m
a=30m
b=?
So, by substituting we have:

Have a nice day!
