Answer:

D) arccsc (x) = arcsin (1/x)

Step-by-step explanation:

Here's how you can prove it: Consider a right triangle with hypotenuse 1 and a side length 1/x. If θ is the angle opposite of 1/x, then:

sin θ = 1/x

and

csc θ = x

Solving for θ:

θ = arcsin (1/x)

θ = arccsc (x)

Therefore:

arccsc (x) = arcsin (1/x)

If CR = 2, RA = 3 , and BC = 10, find CS. 4 6 6 2/3 15

OlgaM077 [116]

Answer:

CS = 4

Step-by-step explanation:

From the figure below;

Triangle ABC is similar to triangle RSC

Therefore, the ratio of the corresponding sides in the two triangles is equal;

That is;

$\frac{AB}{RS}=\frac{AC}{RC}=\frac{BC}{SC}$

In this case, CR = 2 , RA = 3 and BC = 10 we are required to determine CS

But; $\frac{AC}{RC}=\frac{BC}{SC}$

AC=CR + RA

= 5

Assuming CS is y, then

$\frac{5}{2}=\frac{10}{y}$

$y=\frac{10(2)}{5} \\ = 4$

Therefore, CS is 4

-2 goes on the number -2.
-2 1/2 on the 2nd line after 2.
-5/2 or -2 1/2 goes on the 2 line before -2.
And 9/4 or 2 1/4 goes on goes on the 1st line after 2.
