I do believe that it is B.
Sorry I don't have much of an explanation.
The height of the kite will be 53.32 feet above the ground.
<h3>What is trigonometry?</h3>
The branch of mathematics sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.
Given that:-
- The boy is flying a kite, holding his hands a distance of 3.5 feet above the ground and
- letting all the kite's strings play out. He measures the angle of elevation from his hand to the kite to be 29°. If the string from the kite to his hand is 110 feet long, what is the total vertical height?
The height of the kite above the ground will be calculated as:-
H = Sin(29) x 110
H = 53.32 feet
The hand of the boy is 3.5 above the ground so the total height H(t) of the kite above the ground will be:-
H(t) = 53.232 + 3.5
H(t) = 56.28 feet.
Therefore the height of the kite will be 53.32 feet above the ground.

Answer:
Let's denote:
The cost of buying 1 burger: x
The cost of buying 1 drink: y
Then, we have:
5x + 3y = 13 (1)
3x + 5y = 11 (2)
Add up both sides of (1) and (2):
=> 8x + 8y = 24
=> x + y =3 (*)
Subtract both sides of (1) to (2):
2x - 2y = 2
=> x - y = 1 (**)
From (*) and (**):
x = 2
y = 1
=> The cost of buying 2 burgers and 2 drinks: 2(x + y) = 2(2 + 1) = 6$
Answer:
8 is $230
Step-by-step explanation:because there is a fee of $55 and $25 a week, the $55 is a one time charge and then $25 times 7 weeks is $175 then $55+$75 is $230
Answer:
<em>Answer: False</em>
Step-by-step explanation:
<em>Relations vs Functions</em>
For a given relation between two variables x and y to be a function, it must meet the following condition: every value of x must be related to one and only one value of y.
When the graph of a relation is given, we can easily tell the difference by using the vertical line test as follows:
Imagine a vertical line moving through the x-axis. If any line touches the graph of the relation at more than one point, then the relation is not a function.
If we place vertical lines through the x-axis, they would touch the function twice at some values of x.
Thus, the graph is not a function
Answer: False
