Question

sec={ }
a. (e,r/x):sec0=r/x
b. (e,x/r):sec0=x/r
c. (e,r/y):sec0=r/y
d. (e,y/x):sec0=y/x

Answer 1

Answer:

A choice

Step-by-step explanation:

sec is defined as 1/cos.

cos is again defined as adjacent to hypotenuse.

We know that adjacent is x and hypotenuse is r.

Therefore:- cos is x/r

Now sec is 1/cos = 1/(x/r)

1 ÷ x/r is 1•r/x

Thus:-

sec is r/x
