you can imagine this as a venn diagram. the "or" event would consist of everything in both sides and the middle of the venn diagram because you can choose form either event x <u>or</u> event y.
the "and" event would consist of everything in the middle of the venn diagram because you choice must be a part of both event x <u>and</u> event y.
the complement of an event is just everything that is not included in the event. for example, in a coin flip, the complement of heads is tails. in a dice roll, the complement of {1,2} is {3,4,5,6}
so if you come across these just think "either or" or "both and." and remember that the complement is everything excluding what is listed.
i apologize if this does not help, im not that great at explaining things

Answer:
Our equation is:
Solving this yields that the width of the river is about 77 feet.
Step-by-step explanation:
Part A)
We know that McNeal is 120 feet from the tree. This is the hypotenuse.
And we want to find the width of the river, which is the side opposite from our angle.
Since we want to find the side opposite to our angle and we are given the hypotenuse, we will use the sine ratio:
Our angle is 40°.
The opposite side is unknown. We can let this be <em>w</em> to represent width.
The hypotenuse is 120 feet. Hence, our equation is:
Part B)
Solve for <em>w: </em>

Use a calculator:
The width of the river is about 77 feet.
Answer: x = 15
Step-by-step explanation:
same thing. here's my work:
<em>4x - 5 = 3x + 10</em>
<em>4x - 5 (+ 5) = 3x + 10 (+ 5)</em>
<em>4x = 3x + 15</em>
<em>4x (- 3x) = 3x (- 3x) + 15</em>
x = 15
