If cosine theta almost-equals 0.3090, which of the following represents approximate values of sine theta and tangent theta, for

Zepler [3.9K]

Answer:

$\sin \theta = 0.9511$ and $\tan \theta = 3.078$

Step-by-step explanation:

Given that, $\cos \theta = 0.309$ .

Now, we have to calculate the values of $\sin \theta$ and $\tan \theta$ .

We know the identity that, $\sin^{2}\theta + \cos^{2}\theta = 1$

So, $\sin \theta = \sqrt{1 + \cos^{2}\theta} = \sqrt{1 - (0.309)^{2}} = 0.9511$ {Since $0 \leq \theta \leq 90^{\circ}$ }

Now, $\sec \theta = \frac{1}{\cos\theta} = \frac{1}{0.309} = 3.236$

Then, we know the identity, $\sec^{2}\theta - \tan^{2}\theta = 1$

So, $\tan \theta = \sqrt{\sec^{2}\theta - 1} = \sqrt{(3.236)^{2} - 1} = 3.078$ (Answer) {Since $0 \leq \theta \leq 90^{\circ}$ }

G would be the independent variable, which means the total cost would depend on it since it depends on the number of games you bowl. Y could be any variable, such as T or C.

Answer:

Option C. x = 5

Step-by-step explanation:

To solve this question we should always keep these two points in our mind.

1). In-center of a triangle is formed by the intersection of the angle bisectors of all interior angles of the triangle.

2). In-center of a triangle is equidistant from all three sides of the triangle.

From the figure attached,

In ΔSRT,

∠ASZ ≅ ∠ZSB [ SZ is an angle bisector of angle ASB]

5x - 9 = 16 [ given in the question]

5x = 16 + 9

5x = 25

x = $\frac{25}{5}$

x = 5

Therefore, Option C. is the answer.
