If sis equal to 16,c is equal to 14m and b is equal to 19m ,find the angles of 5he triangle ABC with following work steps

Answers

Answer:

Below in bold.

Step-by-step explanation:

a = 16, b = 19 and c = 14.

By the Cosine Rule:

cos A = (a^2 - b^2 - c^2) / -2bc, so:

cos A  = ( 16^2  - 19^2 - 14^2) / (-2*19*14)

             =   -301 / - 532

             =  0.565789

m < A = 55.54 degrees.

Now Using the Sine Rule:

a / sin A = b / sin B

16 / sin 55.54 = 19/sin B

sin B = 19 * sin 55.54 / 16

         = 15.666 / 16

         = 0.979125

m < B = 78.27 degrees.

Finally

m < C = 180 - 55.54 - 78.27 = 46.19 degrees.

The end behavior of the function is:

So the correct statement is the second one.

How is the end behavior of the graphed function?

For a function f(x), the end behavior is how f(x) behaves when:

x ⇒ ∞x ⇒ -∞

If you look at the graph, you can see that in both ends (left and right) the function ends going upwards. This means that in both limits, the function will tend to positive infinity.

Then the end behavior is:

as x ⇒ ∞, f(x) ⇒ ∞as x ⇒ -∞, f(x) ⇒ ∞

So the true statement is the second one.

The value of x in the right angle triangle is approximately 45 degrees.

How to find an angle in a right angle triangle?

The angle of the right angle triangle can be found as follows:

Therefore, let's find the hypotenuse side using Pythagoras theorem,

6² + 6² = c²

c² = 72

c = √72

c = 8.48528137424

c = 8.5 cm

Hence,

sin x = opposite / hypotenuse

sin x = 6 / 8.5

sin x = 0.70588235294

x = sin⁻¹ 0.70588235294

x = 44.9006818301

What is the measure of angle D?
Enter your answer as a decimal in the box. Round only your final answer to the nearest hundredth.

Answers

Answer:

  29.05°

Step-by-step explanation:

The mnemonic SOH CAH TOA is intended to remind you of the relationship between trig functions and side lengths in a right triangle. In your triangle, the sides adjacent and opposite angle D are given. The relevant relation is ...

  Tan = Opposite/Adjacent

__

Using the given values, we have ...

  tan(D) = (25 ft)/(45 ft) = 5/9

The value of the angle is found using the inverse tangent function.

  D = arctan(5/9) ≈ 29.05°

The measure of angle D is about 29.05°.

The next model of a sports car will cost more than the current model. The current model costs . How much will the price increase in dollars? What will be the price of the next model?

Increase in price:

Price of next model:

Answers

Answer:

Step-by-step explanation:

1. Given that $53000 represents 100% of the original cost. You know that 6.9% as a percentage is equivalent to 0.069 as a decimal.

Increase in price:

           = 53000 * 0.069

           = $3657

2. The question states that the price of the car model is increasing, so you must add the original cost to the increase in price.

Price of next model:

           = 53000 + 3657

           = $56657

What is a square?

It is a polygon with four sides. The total interior angle is 360 degrees. A square's opposite sides are parallel and all sides are equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.

There are two squares.

The perimeter of square x is half the perimeter of square y.

Let the side of the square x be a and the side length of the square y be b. Then we have

Perimeter x = Perimeter y / 2

              4a = 2b

              2a = b

Then the area of the square x will be

Area of square x = (2a)²

Area of square x = 4a²

Then the area of the square y will be

Area of square x = (b)²

Area of square x = b²

Then the area of square x will be one-fourth of the area of square y.

Thus, the correct option is C.

Step-by-step explanation:

The diagonals of a rectangle divide the figure into two pairs of congruent isosceles triangles. The figure is symmetrical about both the vertical and horizontal centerlines. Each corner angle of the rectangle is 90°. Of course, the sum of angles in any of the triangles is 180°.

x=2

Step-by-step explanation:

We must equate f(x)=g(x) ;

x+3=2x^2-3

2x^2-x-6=0, when we solve for x in this equation we get 2 solutions:

x=2, x=-1.5

Since -1.5 is not seen in the table, we consider the value 2.

At x=2 in the table both f(x) and g(x) have the same value 5 and proves f(x)=g(x) has a solution at x=2.

Answer:

x = 2

Step-by-step explanation:

Given:

f(x) = |x| + 3

g(x) = 2x² - 3

From inspection of the table, the equation f(x) = g(x) has a solution when

x = 2 as this is the only value of x when the two functions have the same value of 5.

See attached graph for proof.  The points of intersection are the solutions:  (-2, 5) and (2, 5).  (Since x = -2 is not in the given table, this is not included in the answer to this question).
