Do you mean -(sqrt(2))/2 ?
okay i know that this is in the 3rd quadrant with reference angle 45
so i understand the first part but what i dont get is how i can find the value can you please explain.
sides of triangle are sqrt 2, sqrt 2 , 2 so
cos x also = -sqrt 2 / 2
tan = sin / cos
sec = 1/cos
csc = 1/sin
ctn = 1/tan
sin = -sqrt 2 / 2
cos = -sqrt 2 / 2
tan = 1
cot = 1
sec = -sqrt 2
csc = -sqrt 2
is that right ?
okay now how can i find the value?
yes. Sqrt 2 is approximately 1.41
x = 180 + 45 in degrees
= (1 1/4) pi in radians
thanks for your time but they are also asking for the value of x which i think they mean the value of x in degrees ??
x = 225 degrees
