Secant is a trigonometric function that quantifies the quotient of hypotenuse and the side that is adjacent to the given angle. This is the reciprocal of the cosine function.
cosine = adjacent / hypotenuse = x/h
secant = h / x
Secant equal to -1 means that x and h are numerically equal but opposite in sign.
secant = -1
cosine = 1/secant =1/-1 = -1
arccos (-1) = 180°
Thus, the answer to this item is 180°.

Step-by-step explanation:
f(x) = x2 – 2x + 5
= (-3)²-2(-3)+5
= 9 +6+5
= 20

Step-by-step explanation:
sin S =
is the ratio found.
<u>Step-by-step explanation:</u>
It is given that m∠U = 90°
TS is the hypotenuse = 73 units
UT is the adjacent side of the right angle = 48 units
SU is the base of the triangle = 55 units
Now we have to find the ratio as,
sin S = ![$\frac{opp}{hyp}](https://tex.z-dn.net/?f=%24%5Cfrac%7Bopp%7D%7Bhyp%7D)
sin S = ![$\frac{UT}{TS}](https://tex.z-dn.net/?f=%24%5Cfrac%7BUT%7D%7BTS%7D)
Plugin the values, we will get,
sin S = ![$\frac{48}{73}](https://tex.z-dn.net/?f=%24%5Cfrac%7B48%7D%7B73%7D)
So the ratio was found.
