WE can find the sides if the triangle by apply the Sine rule :

where, a,b & c are the sides of triangle

For eg :

Consider an triangle with one side AB = 5

and angles A = 60, angle B = 45 and angle C= 75

So, substitute the value in the expression of Sine

The sides : AB = 5, AC = 3.66 & BC = 4.4

To obtain the number of locker codes available, the following steps are necessary:

Step 1: Create a diagram to represent the slot for each of the digits, as below;

Step 2: State the number ways that each digit can be used to fill any of the spots, as below:

Given that there are the numbers 0,1,2,3,4,5,6,7,8,9 - a total of 10 numbers,

- The first slot can be filled with any of the digits above, and thus can be filled in 10 ways

- The second slot can be filled with any of the remaining 9 numbers after one of them has already been used to fill the first slot. Thus, there are 9 ways the second slot can be filled.

- The same line of reasoning tells us that the third slot will be filled in 8 ways

- Lastly, the fourth slot will be filled in 7 ways

The diagram below gives a better illustration:

Step 3: Multiply the numbers of ways to find the total number of locker codes that are available, as follows:

Therefore, there are a total of 5040 available locker codes at Lincoln High School

Correct answer = Option C

The third option is correct. That is, the figure could be a rhombus because the 2 lines of symmetry bisect the angles.

What is rhombus?

A rhombus is a quadrilateral that is an equilateral parallelogram and has all of its opposite pairs of sides parallel. Sometimes the word "rhombus" is substituted with "rhomb," and a rhombus is also referred to as a "diamond."

Given: A quadrilateral has exactly 2 lines of symmetry, and both are angle bisectors.

Since the two lines of symmetry in a quadrilateral are angle bisectors, the figure may be a rhombus if the quadrilateral has exactly two lines of symmetry. Figures with four sides and angles are called quadrilaterals. Rectangle is a type of quadrilateral.

Therefore, If a quadrilateral has exactly 2 lines of symmetry, and both are angle bisectors, then the figure could be a rhombus because the 2 lines of symmetry bisect the angles.

Step-by-step explanation:

In order to solve this equation for y, we just need to isolate the variable y in the equation.

So, we have that:

So we have that y = (T - 2x + z) / 3

The horizontal arrows denote that segments RS and VT are parallel. This means that angleR and angleV are congruent. Similarly, angleS and angleT are congruent. They are denoted in blue and red color, respectively:

It is easy to get the graph of the exponential function since x - value = 4 and y - value = 2.

An exponential function is defined by the formula f(x) = x^a, where the input variable x occurs as an exponent. The exponential curve depends on the exponential function and it depends on the value of the x.

The general equation of an exponential function is

The given ellipse is

We use the same process to find f(20).

So, the points are A(15, 19.2) and B(20, 15). To find the distance between these points, we have to use the distance formula

If a square meter of land costs $250 in a certain place, then 1.6 sq. m. of land can be bought there for $400, calculated using the unitary method.

As per the question statement, the cost of per square meter of land in a certain place is $250,

And we are required to calculate the amount of land that can be bought in the above mentioned place for $400.

To solve this question, we will use the unitary method, that is,

Given, the cost of per square meter of land in a certain place is $250,

Or, in $250, one can buy 1 sq. m. of land in this place,

Or, in $1, one can buy (1/250) sq. m. of land,

And, in $400, one can buy [{(1/250) * 400} = (40/25) = (8/5) = 1.6 sq. m.] of land in that place.

The slope of the line that is perpendicular to the line y = - 1x +5 is -1.

The ratio of how much y grows as x grows by a certain amount is known as a line's slope. The slope of a line indicates how steep it is, or how much y rises as x rises. Anywhere along the line, the slope remains constant (the same).

Given:

The equation of the line, y = -x + 5

The slope of the line can be calculated by the intercept form,

so m = -1, Here, m is the slope.

The slope of the perpendicular line will be the opposite

So, M = -1

Therefore, the slope of the line that is perpendicular to the line y = - 1x +5 is -1.

In this case, we have a proportional relationship, since the cost varies directly with the days, this means that as x increases, y increases, and as x decreases, y decreases. A proportional relationship has the form:

y=kx

Where k is the constant of proportionality.

The ratio between them (x and y) is always the same, in this case, the ratio or constant of proportionality is 40, since each day the rent cost increases $40, then:

Constant of proportionality = 40 , replacing 40 for k into the above equation, we get:

equation: y = 40x

We can use this equation to find some pair of values (x,y) to fill the table, like this:

For x equals 2:

y= 40*2 = 80

For x equals 3:

y= 40*3 = 120

For x equals 4:

y=40*4 = 160

For x equals 5:

y=40*5=200

Then, we can fill the table as follows:

We can also use these data to graph the relationship, by taking the point (5,200) and joining it to the origin, we get:

The equation

y = x - 2

is the equation of a line in the slope-intercept form with a slope of 1 and a y-intercept at (0, -2).

You can graph it by locating two points on the line. One point is (0, -2). The other one can be found with the slope. The slope of 1 means that the next point is 1 unit to the left and 1 unit up, respect the previous point. In this case, the next point is (1, -1). After you locate these two points, draw the line that connects them, as follows

the organizer will select from 3 workshop about anthropology and 10 workshops about psychology.

we were asked in how many ways she can select 7 workshops if 2 or fewer must be anthropology

so,

If 2 or fewer must be anthropology,

Then tha means it is either she selects 2 from anthropology and 5 from psychology or 1 from anthropology and 6 from psycology.

that is:

= 3C2 x 10C5 or 3C1 x 10C6

= 3!/(3-2)!2! x 10!/(10-5)!5! + 3!/(3-1)!1! x 10!/(10-6)!6!

= 3x2!/2! x 10x9x8x7x6x5!/5!5! + 3x2!/2! x 10x9x8x7x6!/4!6!

= 3 x 252 + 3 x 210
