In this question, we are given that the co -secant of theta is equal to negative 37 over 35.
00:06
Cosecant, we know, is equal to the radius divided by y.
00:10
And because we know that the radius is always greater than zero, in order for co -secant of theta to be negative here, that means that y must be less than zero.
00:19
Then we also know that the tangent of theta is greater than zero.
00:23
So we know that tangent is y over x, because we already know that y is less than zero.
00:28
In order for a tangent to be greater than 0, you must know that x is less than 0 as well.
00:34
And the only quadrant in which both x and y are less than 0 is in quadrant 3.
00:41
We're given that cosegan of theta is negative 37 over 35.
00:46
So that means that our r must be 37...
