Answer: Choice D

=====================================

Explanation:

Abbreviations:
sec = secant
cot = cotangent
cosec = cosecant (csc is also a widely used abbreviation)

Let's go through the answer choices one by one

Choice A is false because secant involves the hypotenuse

Choice B is false because opposite/adjacent is the ratio for tangent

Choice C is false because cosecant (csc) involves the hypotenuse

Choice D is true. This is the proper ratio for secant. It is the reciprocal of the ratio for cosine. Recall that cosine's ratio is adjacent/hypotenuse.

Komok [63]

Answer:

Option D: 1/3

Step-by-step explanation:

Let

x ------> the entire Stefanie's allowance

we know that

She spends on clothes (1/2)x

She spends on movies (1/6)x

To find out how much more does she spend on clothes that he does on movies, subtract the amount she spends on movies from the amount she spend on clothes

$\frac{1}{2}x-\frac{1}{6}x=\frac{2}{6}x$

Simplify

$\frac{1}{3}x$

therefore

She spends 1/3 more on clothes that he does on movies
