SOLUTION: suppose (theta) is an angle in the standard position whose terminal side lies in quadrannt 2.if sin(theta)=12/13, find the value of sec(theta)

Question 212759: suppose (theta) is an angle in the standard position whose terminal side lies in quadrannt 2.if sin(theta)=12/13, find the value of sec(theta)

If sin(theta) =12/13 in the second quadrant, then the reference triangle has "opposite side" of 12 and hypotenuse 13. This means that the "adjacent side" is 5, and since it is in the second quadrant, it is -5.

Sec(theta) is =.
