Step-by-step explanation:
For this case we have a point given (-6,-8) and we know that this point is terminal side of 0
We can assume that the length of th opposite side is given by:
b=-8 and the length for the adjacent side would be a=-6
And we can find the hypothenuse on this way:
From the definition of sin we know this:
And if we replace we got this:
We can aslo find the cos with the following identity:
And then:
But since both corrdinates are negative we are on the 3 quadrant and then![cos \theta= -\frac{3}{5}](/tpl/images/0439/9858/b1288.png)
