Answer:
Step-by-step explanation:
Here, a = 30, b = 16, C = x
By law of cosines
Steps to solve:
2/3x - 1/5 > 1
~Add 1/5 to both sides
2/3x - 1/5 + 1/5 > 1 + 1/5
~Simplify
2/3x > 1 1/5
~Multiply 3/2 to both sides
2/3x * 3/2 > 1 1/5 * 3/2
~Simplify
x > 9/5
Best of Luck!

<h3>Answer:</h3>
x/tan(x) is an even function
sec(x)/x is an odd function
<h3>Explanation:</h3>
<em>x/tan(x)</em>
For f(x) = x/tan(x), consider f(-x).
... f(-x) = -x/tan(-x)
Now, we know that tan(x) is an odd function, so tan(-x) = -tan(x). Using this, we have ...
... f(-x) = -x/(-tan(x)) = x/tan(x) = f(x)
The relation f(-x) = f(x) is characteristic of an even function, one that is symmetrical about the y-axis.
_____
<em>sec(x)/x</em>
For g(x) = sec(x)/x, consider g(-x).
... g(-x) = sec(-x)/(-x)
Now, we know that sec(x) is an even function, so sec(-x) = sec(x). Using this, we have ...
... g(-x) = sec(x)/(-x) = -sec(x)/x = -g(x)
The relation g(-x) = -g(x) is characeristic of an odd function, one that is symmetrical about the origin.
