What angle is 360 degree?.
The angle 360 degree is called as complete angle.
An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles.
A form of angle that measures 360° is known as a full angle. When two lines meet at a point, an angle is created, and the angle is the width of the space created.
The angle generated in this case is referred to be the complete angle if, after one complete revolution, the final ray corresponds with the incident or initial ray. A round angle and a complete angle are the alternate names. The angle, which corresponds to the center of a circle, is 2 radians, or 360 degrees. A complete angle is made up of four right angles or two straight angles. The amount of rotation makes the angle different from a zero angle.

What is the solution of 2x 3y 13?.
The equation 2x + 3y = 13 has infinitely many solutions.
We know that a linear equation in two variables is of the form ax + by + c = 0, where a, b, c are non-zero real numbers.
Here we have been given a linear equation in two variables 2x + 3y = 13
To find the solution of equation 2x+3y=13, first we solve equation for x and then for any real value of y we find value of x.
We solve this equation for x,
Consider 2x + 3y = 13
2x + 3y - 3y = 13 - 3y .........(subtract 3y from each side of equation)
2x/2 = (13 - 3y)/2 .........(divide each side by 2)
x = (13 - 3y)/2
for any real value of y we can find value of x.
This means, an equation 2x + 3y = 13 has infintely many solutions.
The graph of 2x + 3y = 13 is shown below.
From the graph, the y-intercept of line 2x + 3y = 13 is (0, 4.333)

How do you write a sum?.
Sum is an aggregation of the numbers, quantities etc. It is write as 4 + 4 = 8 ( plus symbol (+ ) represent the sum). Similarly, ∑ (sigma) also represents the sum of numbers.
Addition is an important topic in Mathematics. When we add two or more numbers, the result is defined as the SUM. The added numbers are called addends. The sum of two or more numbers make a new number say total. A plus symbol (+) is used when we add the numbers. Summation (or) sum formula is the sum of consecutive terms of a sequence. To write the sum of more terms, say n terms, of a sequence {an} , we use the summation notation instead of writing the whole sum manually. That is summation symbol which represent the sum is ∑ (sigma). For example, Sum of two numbers say 6 and 7 is equals to 6 + 7 = 13. But in case of "n" numbers the sum is determined as following way. Consider the first n even numbers, i.e., 2,4,6,....,n and we have to calculate the sum of it. As we see the above sequence is in AP with first term, a = 2 and common difference, d= 2. Then the sum formula in AP is S = n/2[ 2a + (n -1)d ]
=> S = n/2 [ 4 + (n-1)2 ]
=> S = n/2 [ 4 + 2n - 2 ]
=> S = n(n+1) or ∑n( n+1,) ; n = 1,2,.......
Hence, the sum of first n even numbers can be written as ∑n( n+1,) ; n = 1,2,.......

I. Find the lope of the line l1 which ha equation 4x − 3y 5 = 0. Ii. Find an equation of the line l2, which pae through the point (1, 2) and which i perpen-dicular to the line l1
iii. The line l1 croe the x-axi at P and the line l2 croe the y-axi at Q. Find the
coordinate of the mid-point of P Q
The coordinates of the midpoint of PQ is (5/8, 1/8)
i. To find the slope of the line l1, you can rearrange the equation 4x - 3y + 5 = 0 to the standard form of y = mx+ b, where m is the slope and b is the y-intercept.
4x - 3y + 5 = 0
3y = -4x + 5
y = (-4/3)x + (5/3)
So the slope of the line l1 is m = -4/3.
ii. To find an equation of the line l2, which passes through the point (1, 2) and is perpendicular to the line l1, you can use the slope-intercept form of a line y = mx + b, where m is the slope and b is the y-intercept. Since line l2 is perpendicular to line l1, the slope of l2 is the negative reciprocal of the slope of l1.
m = -1/(-4/3) = 3/4
We can substitute point (1, 2) into the equation
2 = 3/4 * 1 + b
b = 2 - 3/4
So the equation of the line l2 is y = 3/4 x + (2 - 3/4) = 3/4 x + 1/4
iii. To find the coordinates of the point where line l1 crosses the x-axis, we can set y to 0 and solve for x.
y = (-4/3)x + (5/3)
0 = (-4/3)x + (5/3)
x = 5/4
The point where line l1 crosses the x-axis is (5/4, 0)
Similarly, to find the point where line l2 crosses the y-axis, we can set x to 0 and solve for y.
y = 3/4 x + 1/4
y = 3/4 * 0 + 1/4
y = 1/4
The point where line l2 crosses the y-axis is (0, 1/4)
The midpoint of two points can be found by taking the average of the x and y coordinates.
Midpoint of P and Q = ( (5/4 + 0) / 2, (0 + 1/4) / 2) = (5/8, 1/8)
So the coordinate of the midpoint of PQ is (5/8, 1/8).

From the adjacent image we can identify the points of the graph.
From the points we can easily find y-intercept and gradient.
How can we identify the points.
Line where cut the x-axis and y-axis. Take that location as point.
For writing point observe the distance of x-axis and y-axis
Let say point A=(0,6) and point B=(-3,0)
For find y-intercept we must know gradient first
Gradient formula for two points m=[tex]\frac{y_{2} -y_{1 }}{x_{2} -x_{1 }}[/tex]
Submit Point A and Point B m=[tex]\frac{0 -6}{-3 -0\\}[/tex]
m=[tex]\frac{-6}{-3 \\}[/tex]
m=2
Therefore, Gradient of slope m=2
To find y-intercept, we must solve lin equation
Line equation y=mx+b
m = gradient and b=y-intercept
Submit m in line equation y=2x+b
Submit any one point in the line equation
Take pointA=(0,6)
6=2(0)+b
b=6-2
b=4
Therefore ,y-intercept equals to 4

Two tudent calculated the area of a polygon in the coordinate plane uing different trategie. Explain the two method
Of the two methods for area calculation, the preferred method is the second method because the objects around the polygon are smaller, and easier to calculate their area.
There are several ways to calculate the area of a polygon. Two of them were carried out by the two students in the problem:
Dividing irregular polygons into smaller and more regular shapes. Then determine the area of each shape and add them up to get the area of the polygon.Draw a regular shape such as a rectangle around the polygon. Then divide it into smaller regular shapes (without including the initial polygon) and add up the areas of each. The area of the polygon is the area of the rectangle minus the sum of those smaller areas.Of the two methods for the area of a polygon calculation, the preferred method is the second method because the objects around the polygon are smaller and easier to calculate their area.
