Answer:
The answer to your question is x = 14.7
Step-by-step explanation:
Data
∠A = 20°
∠B = 46
a = 7
b = x
Process
To solve this problem use, the law of sines. This law states that the ratio of a side of a triangle to the sine of the opposite angle is the same for all three sides.
The law of sines for this problem is
x / sin 46 = 7 / sin 20
-Solve for x
x = 7 sin 46 / sin 20
-Simplification
x = 7 (0.719) / 0.342
x = 5.035/0.342
-Result
x = 14.7
The supplies travelled 45ft and it took 0.6min to get to the next floor.
<h3>What is trigonometry?</h3>
Trigonometry is the branch of mathematics dealing with the relationship between the sides of a triangle and the angles.
Analysis:
The supplies distance travelled, distance of first floor from second floor and the ground form a right angled triangle.
so that sin 60 = 39/distance travelled by supplies
distance travelled by supplies = 39/sin 60 = 39/0.866 = 45 feet.
speed = distance / time
time = distance / speed = 45/70 = 0.6 min
In conclusion, the distance and time time taken for the supplies to get to the next floor is 45feet and 0.6 min respectively.

I'm assuming this is multiple choice and you forgot to post the answers. I'll take a guess and say it probably looks something like this:
Because you can't take the square root of a negative number without getting an imaginary result, resulting in the function having a closed domain limit.
Answer:
see below
Step-by-step explanation:
Addition and subtraction are both closed under polynomials.
That means that when we add and subtract polynomials, we will end up with a polynomial
f(x) + g(x) will = always be a polynomial when we start with polynomials
f(x) - g(x) will = always be a polynomial when we start with polynomials
