Answer:
ft
Step-by-step explanation:
Base=b=8 ft
Hyp=c=?
Perp=a=15 ft
Applying Pythagoras theorem
Answer:
Part I: cot(15 degrees) = cot(45 - 30)
Part II: Evaluation is below
Step-by-step explanation:
<em>Everything is done in degrees</em>
<em />
Two angles that differ by 15 degrees that is easy to evaluate is 30 degrees and 45 degrees. The cot(15 degrees) = cot(45 - 30) = 1/tan(45-30) = (1+tan45tan30)/(tan30 - tan45) = (1+ sqrt(3))/(sqrt(3) - 1)
We rationalize this by multiplying 1+ sqrt(3) in the top and bottom, getting:
(4 + 2sqrt(3))/2 = 2 + sqrt(3)
I hope this helps! :)

And u have to do the question correctly...
Cuz I told u the answer......
Hope this helps......
Answer:
323 feet
Step-by-step explanation:
This is basically the Pythagorean Theorem. If you have experience with this formula, you will know that it only works with right triangles. Why are we talking about a triangle when this problem speaks of rectangles? Well, this is because when a rectangle is split diagonally, it is now two separate triangles. The Pythagorean Theorem states that a^2 + b^2 = c^2. To begin, we will take the base and height of the triangle and either square root them or square them. In this case, you will need to square them. When this is done, you will have the numbers 90,000 and 14,400. What do we do with these? We will add them together now. Next, we will take the sum of these two numbers (104,400), and square root it. This leaves you with 323.109888, but, we need to round it to the nearest foot or, the nearest whole number. This will give us 323 feet as our final answer. Glad I was able to help! ;):)
Answer:
Anything. Variables look like anything, because a variable is just a placeholder for whenever you want to put in another number.
Some examples: x, y, Ф, β
