theta is Q4 angle, such that Sin(theta)=-5/8 . So, what is Sec(theta) and tan(theta) in exact values?
Here is exact question:
We need to find x
sqrt (8^2 -5^2) = sqrt (64 - 25 ) = sqrt (39) = x
sec (theta) = r / x = 8/ sqrt (39) = 8sqrt (39) / 39
tan (theta) = y / x = -5/ sqrt (39) = -5sqrt (39) / 39
Thank you!!
