Answer:
C) 5x-70=105
Step-by-step explanation:
As marked in the graph, angle 105 and angle (5x-70) equal to each other because they are vertically opposite angles therefore we have equation C)
In geometry, definitions are formed using known words or terms to describe a new word. There are three words in geometry that are not formally defined. These three undefined terms are point, line and plane.
<span>POINT (an undefined term) </span>
<span>In geometry, a point has no dimension (actual size). Even though we represent a point with a dot, the point has no length, width, or thickness. A point is usually named with a capital letter. In the coordinate plane, a point is named by an ordered pair, (x,y). </span>
<span>LINE (an undefined term) </span>
<span>In geometry, a line has no thickness but its length extends in one dimension and goes on forever in both directions. A line is depicted to be a straight line with two arrowheads indicating that the line extends without end in two directions. A line is named by a single lowercase written letter or by two points on the line with an arrow drawn above them. </span>
<span>PLANE (an undefined term) </span>
<span>In geometry, a plane has no thickness but extends indefinitely in all directions. Planes are usually represented by a shape that looks like a tabletop or wall. Even though the diagram of a plane has edges, you must remember that the plane has no boundaries. A plane is named by a single letter (plane m) or by three non-collinear points (plane ABC). </span>
<span>Undefined terms can be combined to define other terms. Noncollinear points, for example, are points that do not lie on the same line. A line segment is the portion of a line that includes two particular points and all points that lie between them, while a ray is the portion of a line that includes a particular point, called the end point, and all points extending infinitely to one side of the end point. </span>
<span>Defined terms can be combined with each other and with undefined terms to define still more terms. An angle, for example, is a combination of two different rays or line segments that share a single end point. Similarly, a triangle is composed of three noncollinear points and the line segments that lie between them. </span>
<span>Everything else builds on these and adds more information to this base. Those added things include all the theorems and other "defined" terms like parallelogram or acute angle. </span>
Answer: Area (upper bound) = 4527.7056 cm²
Perimeter (lower bound) = 278 cm
<u>Step-by-step explanation:</u>
The length and width of the rectangle have been ROUNDED to the nearest tenth. Let's calculate what their actual measurements could be:
LENGTH: rounded to 87.3, actual is between 87.25 and 87.34
<em>87.25 is the lowest number it could be that would round it UP to 87.3</em>
<em>87.34 is the highest number it could be that would round DOWN to 87.3</em>
WIDTH: rounded to 51.8, actual is between 51.75 and 51.84
<em>51.75 is the lowest number it could be that would round it UP to 51.8</em>
<em>51.84 is the highest number it could be that would round DOWN to 51.8</em>
To find the Area of the upper bound, multiply the highest possible length and the highest possible width:
A = 87.34 × 51.84 = 4527.7056
To find the Perimeter of the lower bound, calculate the perimeter using the lowest possible length and the lowest possible width:
P = 2(87.25 + 51.75) = 278
