Which undefined term is used to define an angle ?
enyata [817]

Point.

<h3>Further explanation</h3>
  • This is one of the classic problems of Euclidean geometry.
  • The angle is determined by three points, we call it A, B, C, with A ≠ C and B ≠ C.  
  • We express an angle with three points and a symbol ∠. The middle point represents constantly vertex. We can, besides, give angle names only with vertices. For example, based on the accompanying image, the angle can be symbolized as ∠BAC, or ∠CAB, or ∠A.  

Types of Angles  

  • The acute angle represents an angle whose measure is greater than 0° and less than 90°.
  • The right angle is an angle that measures 90° precisely.  
  • The obtuse angle represents an angle whose measures greater than 90° and less than 180°.  
  • The straight angle is a line that goes infinitely in both directions and measures 180°. Carefully differentiate from rays that only runs in one direction.

<u>Note:</u>

Undefined terms are the basic figure that is undefined in terms of other figures. The undefined terms (or primitive terms) in geometry are a point, line, and plane.

These key terms cannot be mathematically defined using other known words.

  • A point represents a location and has no dimension (size). It is marked with a capital letter and a dot.
  • A line represent an infinite number of points extending in opposite directions that have only one dimension. It has one dimension. It is a straight path and no thickness.
  • A plane represents a planar surface that contains many points and lines. A plane extends infinitely in all four directions. It is two-dimensional. Three noncollinear points determine a plane, as there is exactly one plane that can go through these points.

Answer:

\sqrt{\frac{9}{4}} < \frac{5}{3} < \sqrt{5} < 2.5

Step-by-step explanation:

Given the following numbers, \sqrt{\frac{9}{4}}, \sqrt{5}, 2.5, and, \frac{5}{3}, let's express each as whole or decimal numbers, to find out the least to the greatest.

\sqrt{\frac{9}{4}} = \frac{\sqrt{9}}{\sqrt{4}}

\frac{3}{2} = 1.5

\sqrt{5} ≈ 2.2

2.5 (already in decimal form)

\frac{5}{3} ≈ 1.7

From the least to the greatest, we have:

\sqrt{\frac{9}{4}} < \frac{5}{3} < \sqrt{5} < 2.5

How many pounds of Brazilian coffee costing $ 6 per pound must be mixed with 27 lbs of Columbian coffee costing $ 4 per pound to
grigory [225]

Answer:

11 2/3 pounds.

Step-by-step explanation:

Let x pounds be the amount in pounds of Brazilian coffee.

x + 27  is the amount of coffee in lbs after the mixing.

So ,working in  values of dollars, we have:

6x + 4*27 = 4.5(x + 27)

6x + 104 = 4.5x + 121.5

1.5x = 121.5 - 104 = 17.5

x = 17.5/1.5 = 11 2/3 pounds answer

What is the position of 9 in the number 932,805?
nevsk [136]
I assume you're using American notation and this number is equal to 932805 (European notation) : then 9 represents 900 000, which is 9 hundred thousand: so 9 s in <span>b. The hundred-thousands place.

(In the European notation it would in in the hundreds place).</span>
