Read the excerpt from The Importance of Being Earnest. And what makes his conduct all the more heartless is, that he was perfectly well aware from the first that I have no brother, that I never had a brother, and that I don’t intend to have a brother, not even of any kind.

How does this excerpt contribute to the development of the plot?

(A)It shows Cecily's unwillingness to marry Algernon.

(B)It foreshadows Lady Bracknell's approval of the marriage.

(C)It illustrates Jack's strength of character.

(D)It shows why Jack does not approve of Algernon.

sec ф = 5/3 (quadrant 4)

let x = base

y = perp

z = hypotenuse

sec ф = hypotenuse/base = 5/3

⇒ z = 5 and x = 3

finding y:

z² = x² + y²

5² = 3² + y²

y² = 25-9

y² = 16

y = 4

now finding all other geometric functions of theta:

sin ф = y/z = 4/5

sin ф = -4/5 (sin is negative in the 4th quadrant)

cos ф = x/z = 3/5

cos ф = 3/5 (cos is positive in 4th quadrant)

tan ф = y/x = 4/3

tan ф = -4/3 (tan is negative in 4th quadrant)

cosec ф = z/y = 5/4

cosec ф = -5/4 (cosec is negative in the 4th quadrant)

cot ф = x/y = 3/4

tan ф = -3/4 (tan is negative in 4th quadrant)

it should be a and d. lmk if i'm wrong xd
