By applying the concepts of <em>trigonometric</em> functions and given that sin θ = 1/2 and 0° < θ < 90°, then the value of the secant of the given angle is \frac{2\sqrt{3}}{3}. (Right choice: A)

<h3>How to determine the exact value of a given trigonometric function based on a known value</h3>

By trigonometry, we understand that the sine is defined by the following function:

\sin \theta = \frac{y}{\sqrt{x^{2}+y^{2}}}      (1)

Where:

  • y - Opposite leg
  • x - Adjacent leg

And the function secant is defined by:

\sec \theta = \frac{\sqrt{x^{2}+y^{2}}}{x}     (2)

If we know that x² + y² = 4 and y = 1, then we find that the secant is:

x² + 1 = 4

x² = 3

x = \sqrt{3}

Secant is postive for 0° < θ < 90°, thus:

\sec \theta = \frac{2}{\sqrt{3}} = \frac{2\sqrt{3}}{3}

By applying the concepts of <em>trigonometric</em> functions and given that sin θ = 1/2 and 0° < θ < 90°, then the value of the secant of the given angle is \frac{2\sqrt{3}}{3}. (Right choice: A)

ollegr [7]

The question is incomplete :

The height, width and Lenght isn't Given. However, we can create an hypothetical scenario, with a height 6, length 8 and width 4

Answer:

192 unit³

Step-by-step explanation:

The volume of the card box :

Recall the volume of box formula :

V = length * width * height

Volume = 8 * 6 * 4

Volume = 192 unit³

This is the procedure for any given dimension of the card deck.

If PQ bisects Angle RPS and measure of angle RPS = 120°, find p and measure of angle RPQ.
Ghella [55]

Answer:

p = 6; RPQ = 60 degrees

Step-by-step explanation:

Because RPS is 120 degrees and it is bisected by PQ (cut into 2 equal parts), we can determine that both sides are 60 degrees. Set the expression 5p+30 equal to 60 to find the value of p.

5p + 30 = 60

5p = 30

p = 6

So now you have determined that p = 6, and the measure of RPQ is 60 degrees.

Hope this helped!

Brandon buys a radio for $45.45 in a state where the sales tax is 7%.
svlad2 [7]
Given : Brandon buys a radio for $45.99 .sales tax rate is 7%.sales tax is a consumption tax imposed by the government on the sale of goods and services.
Let the price of Radio before the sales tax be $x. Sales tax on $x is 7% x.
Price before sales tax + Amount of sales tax= Cost of Radio.
x+7%x =45.99
Or x+0.07x=45.99
1.07x=45.99
Dividing both sides by 1.07.
x= 41.11
Cost of Radio before tax = $41.11
Sales tax paid = 43.99-41.11= 2.88
Tax paid = $2.90 (To nearest cent)

2/5 =.04  

800*.04 =320       x=320

2/5 = 320/800

2/5 =0.4  is equivalent to 320/800=0.4
