Two ropes are attached to a large ballon in a parade. The people holding the ropes are 40 feet apart,and the angle between the t
tankabanditka [31]

Answer:

We'll use the Law of Sines:

Sine (C) / c = Sine (B) / b

Sine (86) / 40 = Sine (52) / b

0.99756 / 40 = 0.78801 / b

0.024939  = .78801 / b

b = .78801 / .024939

side b = 31.5974978949  feet

Sine (42) / a = Sine (86) / 40

(0.66913 / a) = 0.024939

a = .66913 / .024939

side a = 26.8306668271  feet

Using the law of sines, it is found that the distance between the kite and the dog is of 284.77 meters.

<h3>What is the law of sines?</h3>

Suppose we have a triangle in which:

  • The length of the side opposite to angle A is a.
  • The length of the side opposite to angle B is b.
  • The length of the side opposite to angle C is c.

The lengths and the sine of the angles are related as follows:

\frac{\sin{A}}{a} = \frac{\sin{B}}{b} = \frac{\sin{C}}{c}

For the situation described, we have that:

  • The height is opposite to the angle of 42º.
  • The 425 meters are opposite to the angle of 87º.

Hence:

\frac{\sin{42^\circ}}{h} = \frac{\sin{87^\circ}}{425}

Applying cross multiplication:

h = 425\frac{\sin{42^\circ}}{\sin{87^\circ}}

h = 284.77 meters.

What is the volume of a square pyramid if the perimeter of the base is 44 in and the height is 19 in.? Round to the nearest tent
Verdich [7]

Answer:

766.3 square inches

Step-by-step explanation:

The volume of pyramid is given by  

volume = 1/3(area of base) * height of pyramid

Given shape of base is square and

Perimeter of that square is 44inches

We know that perimeter for square is given by 4* length of side

Thus,

44 inches = 4* length of side

 Length of side = 44/4 = 11 inches  

_____________________________________________

Area of square is given by side*side.

Thus, area of square base of pyramid is = 11*11 inches square = 121 inches square

Now that we have area of base and height of pyramid .

Substituting these value in formula for volume of pyramid we have

volume = 1/3(area of base) * height of pyramid

 volume = 1/3*(121) * 19 = 2,299

 volume = 766.33

Volume of square pyramid rounded to nearest tenth is 766.3 square inches
