Answer:
Step-by-step explanation:
I will show you by example. For the sin ratio, we have that the sin of the reference angle is equal to the side opposite the angle over the hypotenuse of the right triangle. We use this example for finding the ratio, knowing the angle:
found on your calculator. Because this is a special angle in a right triangle, we can also say, by looking at a 60 degree reference angle that the side across from the angle measures square root of 3, and the hypotenuse measures 2. So in terms of a radical,
If we don't know the angle, we use the 2nd button on our calculator to find it. For example, if our problem looked like this:
,
we are asked what angle has a sin ratio of 1/2. We find this angle by pressing the 2nd button on our calculator, then the sin button and you will see this on your screen:
Enter either a .5 or a 1/2 after that open parenthesis and hit enter and you'll get the angle measure. That's how you use the inverses to solve for missing angles.

Answer:
11 feet
Step-by-step explanation:
Area formed by the watery pattern is 379.94 square feet.
Since the water is being sent out in circular pattern, the maximum distance at which the water is reaching out will be equal to the radius of the circle as the sprinkler is at the center of the circle.
Area of a circle is given as:
\begin{gathered}Area=\pi r^{2}\\\\ 379.94 = \pi r^{2}\\\\r^{2}=\frac{379.94}{\pi}\\\\ \text{Using pi equal to 3.14, we get}\\\\ r^{2}=121\\\\ r = 11\end{gathered}
Area=πr

379.94=πr

Using pi equal to 3.14, we get

=121
r=11
This means the radius of the circular pattern being formed is 11 feet. So the sprinkler can spread the water 11 feet away from it.

im not sure if that is correct
comment if wrong
*hope it help:))
Answer:
X-coordinate = 3
Step-by-step explanation:
2x - y = 6
<u> x + y = 3 </u>
3x = 9
3x/3 = 9/3
x = 3
2 (3) - y = 6
6 - y = 6
-y = 6 - 6
y = 0
( 3, 0 )
3 is the x-coordinate of your solution.
Answer:
11≤√134≤12
Step-by-step explanation:
11^2 is 121
and 12^2 is 144
so √134 would have to fall between these numbers
