If sinx = -0.40 and tanx > 0, then secx, to the nearest hundreth, is

A) 0.92

B) -0.92

C) -1.09

D) 1.09

So I figured that sin^-1 = -23.57817848, but I don't know how to get sec, can someone help!

I would assume it is in the 3rd quadrant as well

### LogicalTime

There are 2 angles for x that correspond to sin(x) = -0.40
the one you found is in the 4th quadrant, there is one in the 3rd quadrant as well
