Given csc(A) = 60/16 and that angle A is in Quadrant I, find the exact value of sec A in simplest radical form using a rational

Katarina [22]

Answer:

$\displaystyle \sec A=\frac{65}{63}$

Step-by-step explanation:

We are given that:

$\displaystyle \csc A=\frac{65}{16}$

Where A is in QI.

And we want to find sec(A).

Recall that cosecant is the ratio of the hypotenuse to the opposite side. So, find the adjacent side using the Pythagorean Theorem:

$a=\sqrt{65^2-16^2}=\sqrt{3969}=63$

So, with respect to A, our adjacent side is 63, our opposite side is 16, and our hypotenuse is 65.

Since A is in QI, all of our trigonometric ratios will be positive.

Secant is the ratio of the hypotenuse to the adjacent. Hence:

$\displaystyle \sec A=\frac{65}{63}$

The base of a rectangular prism has dimensions of 3 feet by 4 feet.

Ksju [112]

I'm assuming it is asking for surface area.

SA = 2(lw) + 2(hw) + 2(lh)
SA = 2(3*4) + 2(4*8) + 2(3*8)
SA = 2(12) + 2(32) + 2(24)
SA = 24 + 64 + 48
SA = 136 square feet

3(2x+14)divided by w-y if w=8,x=5,y=1 how do i solve this

Viktor [21]

$\frac{3 (2x + 14)}{w - y}$
$w = 8, x = 5, y = 1$

You have to first substitute every variable into its spot in the equation.

 $\frac{3 (2x + 14)}{w-y}$
 $\frac{3 (2*5 + 14)}{8 - 1}$

Then solve.

$\frac{3 (28)}{7} = \frac{84}{7} = 12$
