thank you kind person. Here have a picture for you to dream at night :)
Help, I’m stuck. Thank you very much
1 answer:
If you notice, the container is really just two circles, with a diameter of 4 each, and a square with sides of 10.5.
now, if we just get the area of each circle, keeping in mind their radius is half of the diameter, namely r = 2, and get the area of the 10.5x10.5 square, sum them up, that'd be the surface area of the container.

Answer:
A. 60 degrees
Step-by-step explanation:
Solution to sin(x/2)=(/2)
By looking at this equation, I can identify that the answer must be within the first quadrant since the numerator and denominator are both positive.
Since it is in the first quadrant, the range of the value of the answer must be between 0 degrees less than or equal to x less than or equal to 90 degrees.
I can also identify that this is a 30, 60, 90 degree triangle because it has a and 2 as the numerator and denominator; in this case this tells us that we are dealing with a 30, 60, 90 degree triangle because that is the only triangle with those 2 respective sides.
Once identifying those two pieces of information, we can then determine the answer.
Since sin is equal Opposite/Hypotenuse, we can then substitute the sides of the triangle (, 2) to find the angle (unknown).
So the equation would look like this,
Sinx/2=/2 (
representing the opposite side of the angle; 2 representing the Hypotenuse of the triangle)
We can then conclude that 60 degrees is the unknown angle, due to the nature of a 30 60 90 degree triangle.

Therefore, the answer, 60 degrees, is a solution to the equation "sin(x/2)=(/2)"
