Now, the cosecant of θ is -6, or namely -6/1.
however, the cosecant is really the hypotenuse/opposite, but the hypotenuse is never negative, since is just a distance unit from the center of the circle, so in the fraction -6/1, the negative must be the 1, or 6/-1 then.
we know the cosine is positive, and we know the opposite side is -1, or negative, the only happens in the IV quadrant, so θ is in the IV quadrant, now
recall that
therefore, let's just plug that on the remaining ones,
now, let's rationalize the denominator on tangent and secant,
Answer:$17.16
Step-by-step explanation:first you subtract $0.80 from $15.47 then add $2.49 and get $17.16
Answer:
x = -2, y =-2
Step-by-step explanation:
5x - 6y = 2
-5x - 5y = 20
Add the two equations together to eliminate x
5x - 6y = 2
-5x - 5y = 20
------------------------
-11y = 22
Divide by -11
-11y/-11 = 22/-11
y = -2
Now we can find x
5x -6(-2) =2
5x +12 = 2
Subtract 12 from each side
5x +12-12 =2-12
5x = -10
Divide by 5
5x/5 = -10/5
x = -2
16+3/7-(12+2/5)=16-12+3/7-2/5=4+(3*5-2*7)/35=4+1/35
