Answer:

A  the first choice

Step-by-step explanation:

Sin theta = opp/ hypotenuse

sin A = 12/16

12 must be opposite angle A and 16 must be the hypotenuse

A shooting star forms a right triangle with the Earth and the Sun, as shown below:
Semmy [17]

I found this!!!!

The scientist can use these two measurements to calculate the distance between the Sun and the shooting star by applying one of the trigonometric functions: Cosine of an angle.

- The scientist can substitute these measurements into cos\alpha=\frac{adjacent}{hypotenuse}cosα=

hypotenuse

adjacent

and solve for the distance between the Sun and the shooting star (which would be the hypotenuse of the righ triangle).

Step-by-step explanation:

You can observe in the figure attached that "AC" is the distance between the Sun and the shooting star.

Knowing the distance between the Earth and the Sun "y" and the angle x°, the scientist can use only these two measurements to calculate the distance between the Sun and the shooting star by applying one of the trigonometric functions: Cosine of an angle.

This is:

cos\alpha=\frac{adjacent}{hypotenuse}cosα=

hypotenuse

adjacent

In this case:

\begin{gathered}\alpha=x\°\\\\adjacent=BC=y\\\\hypotenuse=AC\end{gathered}

α=x\°

adjacent=BC=y

hypotenuse=AC

Therefore, the scientist can substitute these measurements into cos\alpha=\frac{adjacent}{hypotenuse}cosα=

hypotenuse

adjacent

, and solve for the distance between the Sun and the shooting star "AC":

cos(x\°)=\frac{y}{AC}cos(x\°)=

AC

y

AC=\frac{y}{cos(x\°)}AC=

cos(x\°)

y

H E L P ASAP HELP<br> !!!!!!!!!!!!!!!!!!!!!!!!!!!
IrinaVladis [17]

Answer:

See each answer bolded below

Step-by-step explanation:

1. Area of the rectangle is 20 * 30 = 600

Area of the 6 circles is 6(25pi)

150pi/600 = 0.7854

1 - 0.7854 = 0.2146

convert to percentage 21.46%

2. 6/16 -> 3/8

Roughly 38% (37.5)

3. 10/24 = 0.41666666667 or 0.4167

41.66

roughly 42%

4. 12/36 -> 1/3

33.3333

33%

What is the unit rate for 875.52 kilometers in 38.4 hours? Enter your answer, as a decimal, in the box.
serious [3.7K]
We are given:
number of kilometers = 875.52 km
time = 38.4 hours

We need to calculate the unit rate, which means that we need to find the number of kilometers in one hour.
To do so, we will simply divide the total number of kilometers by the total time as follows:
unit rate = 875.52 / 38.4 = 22.8 km/hour

Need help solving for Y
solmaris [256]
Well a triangle equals 180 degrees so if you already have 90 then you would need the other 90. By looking at the triangle I would say y=45. I hope I helped! :)
