Explain how
you know you would use sine, cosine or tangent to
solve this. Explain thorougly
C
X
10
B В
Answer:
To solve for x, I would use Cosine.
This is because cosine holds the ratio of adjacent/hypotenuse. Based on the diagram, we can see that HYPOTENUSE = x, so we are solving for x. We know the angle, is 17 degrees. Lastly, we know the triangle leg ADJACENT to the angle is 10 units long. So we would use cosine, implementing the ratio adjacent/hypotenuse. Solving this, we would use cos(17)=10/x. Then our goal is to isolate x, so cos(17)=10/x becomes cos(17)*x=10, we are still trying to isolate x, so, x=10/cos(17). Therefore, our answer x = 10.457 units. cosine would be the best way to go.

plz help me plz help me plz help me I don't want to get grounded the whole summer the question is. the window has the shape of a kite how many square meters of glass were used to make the window?n
Answer:
1800
Step-by-step explanation:
Just find the area of all the triangles and add
Answer:
18 metres squared
Step-by-step explanation:
it looks like you want to find the area of the kite as a whole, and lucky for you, the kite is conveniently cut into right triangles.
to find the area of a right triangle, you use the equation
A = (b × h)/2
where A is the area, b is the base, and h is the height.
now we plug in the numbers for each individual area and solve for the total area.
let's start with the 1st triangle, where it's base is 30cm and the height is 25 cm.
A = (30 × 25)/2
A = 375 cm squared
now the next one whose base is 30 and it's height is also 25 (We just did this last time so the area is the same)
A = 375 cm squared
now we'll do the next one whose base is 30 and height is 35.
A = (30 × 35)/2
A = 525 cm squared
and the last one is the same as the one we just did so I'll just copy the other answer.
A = 525 cm squared
alright now we'll add up all of the areas we just found to get the total area of the kite.
Total A = 375 + 375 + 525 + 525
Total A = 1800 cm squared
now we will divide our total by 100 because it takes 100 centimetres to get 1 metre and what we have right now is centimetres.
1800/100 = 18 metres squared.

I need help on this question
Answer:
I think you need to combine the equations, which would end with 26x - 2, and to solve for x just isolate it by adding to the other side which would look like 26x = 2
Then divide 26 on both sides, 26x/26 = 2/26
You should end with x = 1/13
explain why n(n-1) must be an even number
n & n - 1 are two consecutive numbers which means one of is surely even and the other one is odd.
_______________________________
Suppose that n is an even number;
So we can right n like this :
n = 2t
Thus :
n - 1 = 2t - 1
_______________________________
n( n - 1 ) = 2t( 2t - 1 ) = 2 ( 2t^2 - t )
= 2 ( q ) = 2q
The number obtained is a multiple of 2, so it is definitely even because all numbers are even multiples of 2.

The diameter of a circle is 2 inches. What is the circle's circumfere
Use 3.14 for u.
PLS HELP!!!
Answer:
[tex]6.28\:\mathrm{in}[/tex]
Step-by-step explanation:
The circumference of a circle is given by [tex]C=2r\pi[/tex], where [tex]r[/tex] is the radius of the circle. Since all radii of a circle are exactly half the length of all diameters of a circle, if the diameter is 2 inches, we know the radius is 1 inch.
Therefore, we have:
[tex]C=2(1)\pi=2\cdot 1\cdot 3.14=\boxed{6.28\:\mathrm{in}}[/tex]
Answer:
6.28in or 6.3in
Step-by-step explanation:
All I did was multiply pie by diameter or multiply it by its radius, which is 1.
C = 2(3.14)(1)
= 6.28
or
C = (3.14)(2)
= 6.28

Find the 8th term of the arithmetic sequence - 2x + 7,4x + 1, 10x – 5, ...
Answer:
Step-by-step explanation:
a1 = -2x + 7
d = 4x + 1 - (-2x + 7)
d = 4x + 1 + 2x - 7
d = 6x - 6
n = 8
a8 = -2x + 7 + (n-1)*d
a8 = -2x + 7 + (8 -1 ) * (6x - 6)
a8 = -2x + 7 + 7 * (6x - 6)
a8 = -2x + 7 + 42x - 42
a8 = 40x - 35

On a test that has a normal distribution, a score of 49 falls three standard deviations below the mean, and a score of 59 falls two standard deviations above the mean. Determine the mean of this test.
The mean of the test that has a normal distribution is 55.
What is the mean of the test?Let's denote the mean of the test by μ, and the standard deviation by σ. We can use the information given to set up a system of two equations:
49 = μ - 3σ equation (1)
59 = μ + 2σ equation (2)
To solve for μ, we can eliminate σ by adding equations (1) and equation (2) to get:
49 + 59 = μ - 3σ + μ + 2σ
Simplifying, we get:
108 = 2μ - σ
We can also solve for σ by subtracting equation (1) from equation (2) to get:
59 - 49 = μ + 2σ - (μ - 3σ)
Simplifying, we get:
10 = 5σ
Therefore, σ = 2.
Substituting this value of σ into the equation we found earlier, we get:
108 = 2μ - σ
108 = 2μ - 2
Solving for μ, we get:
2μ = 108 + 2
2μ = 110
μ = 110/2
μ = 55
Therefore, the mean of the test is 55.
