A kite is flying at a height of 65 m attached to a string. If the inclination of the string with the ground is 31°, find the length of string.
Show your work please
Answer:
let KL be the string PL be perpendicular distance between them. and KL be height of kite flying.
in right angled triangle
relationship between perpendicular and hypotenuse is given by sin angle
sin 31°=p/h
h=65/sin31
KP=126.2m
the length of string is 126.2m
Answer:
127.45 m
Step-by-step explanation:
Given :-
Height of kite = 65 m .Inclination of string = 31° .To Find :-
The length of the string .Solution :-
Here we need to find out the length of the string here if we imagine a right angle triangle in which the height of the kite will be the perpendicular of the triangle and the length of the string will be the hypotenuse of triangle .
And the angle between the the string and the ground will be 31°.
Here we can use ratio of sine as ,
> sin∅ = p/h
> sin 31° = 65m/ h
> h = 65m/sin 31°
> h = 65m/0.51
> h = 127 .45 m

Please answer!!!!!!!
Answer:
7.2 inches
Step-by-step explanation:
First, we find the length of the legs, which are the sides that are parallel to the x- and y-axis.
The leg parallel to the x-axis is 6 inches long.
The leg parallel to the y-axis is 4 inches long.
After finding the length of both legs, we can use the Pythagorean Theorem to find the length of the hypotenuse: a² + b² = c²
a and b being the legs, and c being the hypotenuse
6² + 4² = c²
36 + 16 = c²
52 = c²
√52 = c
c ≈ 7.2 inches

Answer:
m=3.5h
Step-by-step explanation:
Just by looking at this, you know that it won't be either of the adding equations because it only works for the bottom input and output. So, we'll just look at the multiplying ones.
We know that multiplying should get us a bigger number (unless it's a fraction), so the equation h=3.5m won't work very well with this because h would be getting smaller not bigger.
That leaves us with m=3.5h.
To check this, I'll multiply 3.5 by 4 to see if it equals what m is on the table. Sure enough, it's 14. This also works with 2.5 and 8.75.
The length of each side of a cube is x + 1 inches. What is the volume of the cube in cubic inches?
Answer:
V = x³ + 3x² + 3x + 1 in³
Step-by-step explanation:
The volume (V) of a cube is calculated as
V = s³ ( where s is the side ) , then
V = (x + 1)³
= (x + 1)(x + 1)(x + 1) ← expand second pair using FOIL
= (x + 1)(x² + 2x + 1) ← distribute
= x³ + 2x² + x + x² + 2x + 1 ← collect like terms
= x³ + 3x² + 3x + 1

Three vertices of a parallelogram are shown in the figure below.
Give the coordinates of the fourth vertex.
(-3,9)
(0,-3) (6,-6)
Given:
The three vertices of the parallelogram are (-3,9), (0,-3), (6,-6).
To find:
The fourth vertex of the parallelogram.
Solution:
Consider the three vertices of the parallelogram are A(-3,9), B(0,-3), C(6,-6).
Let D(a,b) be the fourth vertex.
Midpoint formula:
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
We know that the diagonals of a parallelogram bisect each other. So, the midpoints of both diagonals are same.
Midpoint of AC = Midpoint BD
[tex]\left(\dfrac{-3+6}{2},\dfrac{9+(-6)}{2}\right)=\left(\dfrac{0+a}{2},\dfrac{-3+b}{2}\right)[/tex]
[tex]\left(\dfrac{3}{2},\dfrac{3}{2}\right)=\left(\dfrac{a}{2},\dfrac{-3+b}{2}\right)[/tex]
On comparing both sides, we get
[tex]\dfrac{3}{2}=\dfrac{a}{2}[/tex]
[tex]3=a[/tex]
And,
[tex]\dfrac{3}{2}=\dfrac{-3+b}{2}[/tex]
[tex]3=-3+b[/tex]
[tex]3+3=b[/tex]
[tex]6=b[/tex]
Therefore, the fourth vertex of the parallelogram is (3,6).

(-2. 8) and (7.-4)
Answer:
y-8=-4/3(x+2)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-4-8)/(7-(-2))
m=-12/(7+2)
m=-12/9
simplify
m=-4/3
y-y1=m(x-x1)
y-8=-4/3(x-(-2))
y-8=-4/3(x+2)
