Answer:
2.
a)1
b)1
c)1
Step-by-step explanation:
There's some identity trigonometric equation, which are valid for all angles,and they doesn't depends on the measure of angle!
some of em are follows:. (x is the given angle)
- sin(x)^2+cos(x)^2=1
- cosec(x)^2=1+cot(x)^2
- sec(x)^2=1+tan(x)^2
You can remember these identity, its gonna help alot.
now back to question,. {x is representing angles)
for (a) sin(x)^2+cos(x)^2=1, this is true for all x, dat means that for all the angle given in question(for ,15°,30°,45°,60° and 120°),we will get 1
for(b) ,
cosec(x)^2=1+cot(x)^2
i.e, cosec(x)^2-cot(x)^2=1, again this is true for all x dat means that for all the angle given in question ,we will get 1
for (c),
sec(x)^2=1+tan(x)^2
i.e,sec(x)^2-tan(x)^2=1,again this is true for all x, dat means that for all the angle given in question ,we will get 1

When x repeats it is not a function so (0,1) or (0,8) could be removed

Answer:
241.5 ft^2
Step-by-step explanation:
First, find the area of the deck. A = LW. L = 20, W = 16.
20 x 16 = 320.
Now that we have found the area of the deck, let's find the area of the garden. A =
. r = 5.
A = (pi)5^2
A = 25(pi) pi = 3.14
A = 78.5
Since the deck will not cover the garden, we must subtract the area of the garden from the total area of the deck.
320 - 78.5 = 241.5
So it would rotate to a right angle with would be
204{2}-2=12
204-50= would equal 151 but, you would have to round this number too
150.
so your answer would be 150.
