Usually if it a triangle with 2 angles and an x

you will add the 2 angles and rearrange to give the answer

Step-by-step explanation:

Hope this helps!!!

Answer:

A right triangle has one angle measuring 90 degrees. The side opposite this angle is known as the hypotenuse (another name for the longest side). The length of the hypotenuse can be discovered using Pythagoras's theorem, but to discover the other two sides, sine and cosine must be used. These are trigonometric functions of an angle.

In the diagram below, one of the angles is represented by the Greek letter θ. (pronounced "the - ta"). Side a is known as the "opposite" side and side b is called the "adjacent" side because of their positions relative to the angle θ.

The vertical lines "||" around the words below mean "length of."

So sine, cosine and tangent are defined as follows:

Step-by-step explanation:

So sine, cosine and tangent are defined as follows:

sine θ = |opposite side| / |hypotenuse|

cosine θ = |adjacent side| / |hypotenuse|

2 more molecules are there at sea level compared to at an altitude of 33Km and 5 more molecules are there at  sea level compared to at an altitude of 50Km.

We have been told that there are less molecules in a cubic meter of air the higher in altitude we will go.

Part : A

Number of molecules at sea level = 1025 molecules

Number of molecules at an altitude of 33 km = 1023 molecules

Difference between number of molecules at sea level and number of molecules at an altitude of 33 km =  1025 - 1023 = 2 molecules

Part : B

Number of molecules at sea level = 1025 molecules

Number of molecules at an altitude of 50 km = 1020 molecules

Difference between number of molecules at sea level and number of molecules at an altitude of 50 km =  1025 - 1020 = 5 molecules.

So, we can conclude that  2 molecules are more at sea level compared to at an altitude of 33Km and 5 molecules are more  at sea level compared to at an altitude of 50Km.

Answer:

Step-by-step explanation:

Let the sides be:

According to question are given:

Use Pythagorean to find the length of hypotenuse:

The first option is discarded, as all sides should be positive. With a = 1 we get negative value for c.

So a = 17 cm.

Find the other sides:

Find the perimeter:

Answer:

40 cm

Step-by-step explanation:

Pythagoras Theorem

[tex]a^2+b^2=c^2[/tex]

where:

Let a be the shorter leg.

If the hypotenuse is 1 cm longer than twice the shorter side then:

[tex]\implies c = 2a + 1[/tex]

If the hypotenuse is 2 cm longer than the other side then:

[tex]\implies c = b + 2[/tex]

Equate the two expressions for c and solve for b:

[tex]\implies b+2=2a+1[/tex]

[tex]\implies b=2a-1[/tex]

Substitute the expression for c involving a, and the expression for b involving a, into Pythagoras Theorem and solve for a:

[tex]\implies a^2+(2a-1)^2=(2a+1)^2[/tex]

[tex]\implies a^2+4a^2-4a+1=4a^2+4a+1[/tex]

[tex]\implies a^2-4a=4a[/tex]

[tex]\implies a^2-8a=0[/tex]

[tex]\implies a(a-8)=0[/tex]

[tex]\implies a=0, \quad a=8[/tex]

Since the length of a side cannot be zero, a = 8.

The perimeter of a two-dimensional shape is the distance around the outside.   Therefore, the perimeter of the triangle is the sum of its sides:

[tex]\begin{aligned} \implies \textsf{Perimeter}&=a+b+c\\&=a+(2a-1)+(2a+1)\\&=5a\end{aligned}[/tex]

Substitute the found value of a into the expression for the perimeter:

[tex]\begin{aligned} \implies \textsf{Perimeter}&=5(8)\\&=40\sf \; cm\end{aligned}[/tex]

Therefore, the perimeter of the triangle is 40 cm.

The equation of the line passing through  (-4,-6), (5,-6) will be y = -6

In the given question, it is stated that the line passes through points  (-4,-6), and (5,-6). We need to find out an equation of the line that satisfies the given condition.

Firstly, we will need to find out the slope of the line. We can find the slope by using the point-slope form which is represented by:

=> [tex]m = \frac{y_{2}-y_{1} }{x_{2} - x_{1} }[/tex]

Putting values (x₁, y₁) =  (-4,-6) and (x₂, y₂) = (5,-6) we get:

=> [tex]m = \frac{-6+ 6 }{5+ 4 }[/tex]

=> m = 0

We get slope m = 0. Now, putting the value of slope into the point-slope form and taking (x₁, y₁) =  (-4,-6), we get values:

=> y - y₁ = m(x - x₁)

=> y + 6 = 0(x + 4)

=> y = -6

Hence, we get the equation of line y = -6

∠ GHI = 17°

Step-by-step explanation:

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ HIJ is an exterior angle of the triangle , then

∠ HJI = ∠ GHI + ∠ IGH , that is

7x - 18 = 2x - 3 + 2x + 15

7x - 18 = 4x + 12 ( subtract 4x from both sides )

3x - 18 = 12 ( add 18 to both sides )

3x = 30 ( divide both sides by 3 )

x = 10

To answer this question, first we need to properly understand the definition of median and mean, and also understand what it means to be "roughly symmetrical".

Let's start with the definition of median.

"the median is the value separating the higher half from the lower half of a data sample"

If we have an odd amount of elements in our dataset, the median is literally the middle element of our set.

Example:

We have four elements below 3, and four elements above 3, therefore, the median of this dataset is 3.

If we have an even amount of elements, the median is the mean between the two elements in the middle.

Example:

The elements in the middle are 1 and 2. This means our median is

1.5.

Now, let's understand the mean.

By definition, The Arithmetic Mean is the average of the numbers: a calculated "central" value of a set of numbers, given by the sum of all elements divided by the amount of elements.

Examples:

Now that we know what mean and median exactly are, let's try to understand what it means to be "roughly symmetrical".

When talking about histograms, Close to symmetric means the data are roughly the same in height and location on either side of the center of the histogram.

As the histogram gets closer to symmetric, the mean approaches the middle values, to be more specific, If the histogram is close to symmetric, then the mean and median are close to each other.

Since the statement says "roughly symmetrical" this is the only thing we can claim. If we have more values to the right in our roughly symmetrical distribution, the mean will be a little bit bigger than then median, and if we have more values to the left in our roughly symmetrical distribution, the mean will be a little bit smaller than then median.

What is Arithmetic ?

The study of the characteristics of the standard operations on numbers, including addition, subtraction, multiplication, division, exponentiation, and root extraction, constitutes the fundamental subject of arithmetic. Giuseppe Peano, an Italian mathematician, formalised arithmetic in the 19th century with the help of his Peano axioms, which are still crucial to the modern study of mathematical logic. There are only a few artefacts from the early history of mathematics that may have shown how addition and subtraction were first thought of. The best-known of them is the disputedly interpreted Ishango bone from central Africa, which dates from between 20,000 and 18,000 BC.
