Answer:
Step-by-step explanation:
7-x=-2
-x=-2-7
-x=-9
x=9
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:
it should be 319
Step-by-step explanation:
19? Lol........................
The answer is 42 mpg, all you need to do is divide 126/3 or 210/5 and they both equal 42.
