Find the missing angle.

-6,7 is in 2nd Quadrant of a coordinate plane because the coordinate of x is negative integer and the coordinate of y is positive integers.

It is possible to find any point in a 2D plane or 3D space using coordinates, which are ordered pairs of points. We may have observed the use of grids in mathematics. We can plot any point using these grids and its coordinates.

Cartesian coordinates, also known as the coordinates of a point in a 2D plane, are two integers, or occasionally a letter and a number, that identify a specific point's precise location on a grid. This grid is referred to as a coordinate plane.

The X-axis is the horizontal axis and the Y-axis is the vertical axis of a coordinate plane, which has four quadrants.

To plot -6, 7 point on coordinate first we find the point -6 on the left side of plane on x axis. the we go upward and find point y=7 parallel to y axis.

this point is -6,7.

Therefore, the area of the given trapezoid is 16.82 square m.

The slope shows a change in the amount of fuel left in each mile. Since the slope is -0.04, the amount of fuel left drops by 0.04 gallons each mile

The slope of a line governs its steepness. Using mathematics, the gradient is expressed as "gradient overflow" (the change in y divided by the change in x). The slope is the ratio of the vertical (rise) to the horizontal (run) change in distance between any two sites. Every time the equation for a straight line is written as y = mx + b, the slope-intercept representation of the equation is utilized. At the location of the y-intercept, the line has a slope of m, b, and c. (0, b). As an example, the y-intercept of the equation y = 3x - 7 has a value of 3. (0, 7).

given

An equilateral triangle has acute angles.

Acute angles are having measurement less than 90 degrees.

The  sum of angles of the triangle must always be equal to 180 degrees.

When 3 angles are equal then the measure of each of them will be given by

3x= 180

x= 180/2= 60 degrees

The  sum of angles of square always equal 360 degrees. When 4 angles are equal then the measure of each of them will be given by

4x= 360

x= 360/4= 90 degrees

A square has four right angles.

The  sum of angles of pentagon always equal 540 degrees. When 5 angles are equal then the measure of each of them will be given by

5x= 540

x= 540/5= 108 degrees

A regular pentagon has 5 obtuse angles.

The  sum of  interior angles of heptagon always equal 900 degrees. When 7 angles are equal then the measure of each of them will be given by

7x= 900

x= 900/7= 128.57 degrees

A regular heptagon has 7 obtuse angles.

So only equilateral triangle has acute angles.

Positive, negative, and zero are all examples of integers.

The Latin word "integer" signifies "whole" or "intact."

As a result, fractions and decimals are not included in integers.

All whole numbers and negative numbers are considered integers.

This means that if we combine negative numbers with whole numbers, a collection of integers results.

An integer, which can comprise both positive and negative integers, including zero, is a number without a decimal or fractional portion.

Here are a few instances of integers: -5, 0, 1, 5, 8, 97, and 3,043. a collection of numbers, denoted by the symbol Z.

According to our question-

First digit: x

Second digit: x + 2

Three-digit number Equals x + 4

Fourth digit: x + 6

The difference between the opposite of the third and the first two sums up to 55.

x + x + 6 = -(x + 4) + 55

x + x+6 = (-x - 4) + 55

2x + 6 = -x + 51

assemble similar terms

2x + x = 51 - 6

3x = 45

x = 15

Therefore,

First digit: x = 15

Second digit: 15 + 2 + x = 17

Third number: 15 + 4 + 4 = 19

Fourth digit: x+6 = 15+6 = 21
