The mean of the data is 1097.5

A mean in math is the average of a data set, found by adding all numbers together and then dividing the sum of the numbers by the number of numbers. For example, with the data set: 8, 9, 5, 6, 7, the mean is 7, as 8 + 9 + 5 + 6 + 7 = 35, 35/5 = 7.

Mean = summation of item /number of items

summation of item = 4390

number of items = 4

therefore mean = 4390/4

= 1,097.5

therefore the mean if the data is 1,097.5

In a right triangle, the tangent of an acute angle is the ratio of the length of the opposite side to the length of the adjacent side, the sine of an acute angle is the ratio of the length of the opposite side to the length of the hypotenuse, and the cosine of an acute angle is the ratio of the length of the adjacent side to the length of the hypotenuse.

Using the side lengths given in the problem, we can identify that angle B is the acute angle opposite the side with length 5.

So, we have:

tanB = opposite/adjacent = 12/5

sinB = opposite/hypotenuse = 12/13

cosB = adjacent/hypotenuse = 5/13

Therefore, the values of the trigonometric functions for angle B in this right triangle are:

tanB = 12/5

sinB = 12/13

cosB = 5/13

In response to the query, we have that The Pythagorean identity for theta = 30° is therefore confirmed since sin(30°) + cos(30°) = 1.

The fundamental Euclidean geometry relationship between the three sides of a right triangle is the Pythagorean Theorem, sometimes referred to as the Pythagorean Theorem. This rule states that the areas of squares with the other two sides added together equal the area of the square with the hypotenuse side. According to the Pythagorean Theorem, the square that spans the hypotenuse (the side that is opposite the right angle) of a right triangle equals the sum of the squares that span its sides. It may also be expressed using the standard algebraic notation, a2 + b2 = c2.

This trigonometric identity is valid for all theta values. Because it is connected to the geometry-related Pythagorean theorem, it is known as the Pythagorean identity.

According to Pythagorean theory,

[tex]Cos(theta)^2 + Sin(theta^)2 = 1[/tex]

So, you can easily include that value into the equation and simplify it if you need to assess sin(theta) + cos(theta) for a certain value of theta:

[tex]Cos(theta)2 + Sin(theta)2 = 1\\Sin(2) + Cos(30)\\If theta = 30, then 2(30) = 1.\\(1/2)\\c^2 + (√3/2)\\c^2 = 1 \s1/4 + 3/4 = 1 \s1 = 1[/tex]

The length of the third side is 9.

A right-angled triangle is a triangle in which one of its angles is a right angle, meaning it measures exactly 90 degrees (π/2 radians). The other two angles are acute angles, meaning they measure less than 90 degrees.

In a right-angled triangle, the side opposite the right angle is called the hypotenuse. The other two sides are called the legs. The leg opposite to an acute angle is called the opposite side, and the leg adjacent to that angle is called the adjacent side.

The Pythagorean theorem is a fundamental concept in right-angled triangles. It states that the sum of the squares of the lengths of the legs of a right-angled triangle is equal to the square of the length of its hypotenuse. This theorem is often used to calculate the length of one side of a right-angled triangle when the lengths of the other two sides are known.

Let's call the missing side of the right triangle "x". We can use the Pythagorean theorem to solve for x, which states that in a right triangle, the sum of the squares of the two shorter sides (legs) is equal to the square of the length of the longest side (hypotenuse).

So, we have:

x² + 7² = (√130)²

Simplifying:

x² + 49 = 130

x² = 81

Taking the square root of both sides, we get:

x = 9
