First, use distributive property on the right half.
2 * 5 = 10
2 * 2n = 4n
4n - 9 = 10 + 4n
Add 9 to both sides
4n = 19 + 4n
Subtract 4n from both sides
0 = 19
But thats not true. Therefore, there is no solution.
The reciprocal is 17/2 cause all you do is just flip the fraction
Hello,
Let's assume k the ratio.

Answer:

Step-by-step explanation:
Given that the angle
is located in Quadrant II; and

In Quadrant II, x is negative and y is positive.

To find
, we first determine the opposite angle of
.
This will be done using the Pythagoras theorem.

Therefore:
