Answer:
x = 21
Step-by-step explanation:
ALL triangles add up to 180 degrees
180 = 22 + 57 + (5x - 4)
180 = 79 + (5x - 4)
101 = 5x - 4
105 = 5x
21 = x

Find cosx and tanx
Answer:
Cos(x) = sqrt(55) / 8; tan(x) = 3/sqrt(55)
Step-by-step explanation:
Sine is opposite over hypotenuse. So we get that the opposite is 3 and the hypotenuse is 8. To find the adjacent (which we'll need for cosine and tangent), we can use pythagoras' theorem. Therefore, 8^2 = 3^2 + A^2, where A is the adjacent. A then must equal sqrt(64-9) = sqrt(55).
Cosine is adjacent over hypotenuse, which is then sqrt(55) / 8. Tangent is opposite over adjacent, which is then 3 / sqrt(55) or (sqrt55)*3/55

Using the formula below, calculate the z-score for the listed data points. z-score: zx = x − μ σ z1 = z5 = z6.5 =
Answer:
z1 = -1.95
z5 = 0.05
z6.5 = 0.8
Step-by-step explanation:
The value of the z score for a mean of 4 and standard deviation is 1.
What is Z score?The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
z = (x - μ)/σ
Where x is the raw score, μ is the mean and σ is the standard deviation.
Let us assume that μ = 4, σ = 2, hence for x = 6:
z = (6 - 4) / 2 = 1
The value of the z score for a mean of 4 and standard deviation is 1.

What is the volume of this pyramid?
Answer:
150 cm
Step-by-step explanation:
It's 150 cm because if you multiply L x W x H, you will get your answer. So it would be 6 x 5 x 5 = 150.
solve the system by substitution 3x-y=10 2x=y
Answer
X=10 and y=20
Step-by-step explanation:
since y=2x, you need to substitute that into the equation to get:
3x-(2x)=10
And evaluate:
x=10
Then substitute 10 into the equation: 2x=y:
2(10)=y
evaluate:
20=y
Now go back to the original equation to check your answer and substitute the values in:
3(10)-(20)=10
30-20=10
10=10
In three to five sentences, explain the importance of sentence structures in good writing.
Answer:
Sentence structure needs to simple, standalone, Grammarly justified and able enough to convey the writer thoughts and feelings clearly
Step-by-step explanation:
Sentence structure is very essential to convey the idea of the writer clearly. It is just like the skeleton of a write up and hence its framework needs to be clear and able enough to express the real sense. The structure of sentence needs to be complete with adequate grammar and punctuations. A good sentence must be able to express a complete idea on its own.

Answer:
Step-by-step explanation:
It all depends on how many people are in your class.
To calculate probability
Determine a single event with a single outcome.
Identify the total number of outcomes that can occur.
Divide the number of events by the number of possible outcomes.
To determine the probability, Use the formula
What is the formula of probability?
P(A) is the probability of an event “A” n(A) is the number of favourable outcomes. n(S) is the total number of events in the sample space.
P(A | B) = P(A∩B) / P(B)

Solve the system of equations using subsititution.
y = 2x - 3
y + 5 = 3x
Answer:
(2,1)
x = 2
y = 1
Explanation:
Check the image
Answer:
(2,1)
Step-by-step explanation:
Since we already have an equation for y, all we need to do is plug that into y in the other equation.
y + 5 = 3x
(2x - 3) + 5 = 3x
2x - 3 + 5 = 3x
2x + 2 = 3x
2 = x
Now that we know y, we just need to plug the value of x into the equation.
y = 2(2) - 3
= 4 - 3
= 1
5x + 8 = 23
Solve x.

Answer:
X=3
