A= 10 add 7 to the 3
mr Goodwill [35]3 years ago
5 0

Answer:

<h2>10</h2>

Step-by-step explanation:

<em>The answer is 10 because 7 + 3 equals 10!</em>

<em></em>

<em>This can be proven by adding 7 + 3 or by subtracting in a certain way.</em>

<em>7 + 3 = ?</em>

<em>7 + 1 = 8</em>

<em>7 + 2 = 9</em>

<em>7 + 3 = 10</em>

<em></em>

<em>You can show more work by subtracting your answer or 10 in this case, which means that you subtract 7 by 10 or 3 by 10, either way is ok.</em>

<em></em>

<em>If you subtract 7 by 10, ( 10 - 7 ) then you get 3</em>

<em>If you subtract 3 by 10, ( 10 - 3 ) then you get 7</em>

<em>If the number you subtracted matches the number that you didn't subtract, then your answer is correct.</em>

<em></em>

<em>Hope this helps! <3</em>

Answer:

A=60 inches by 72 inches

B=increased 600%

Scale is 6 times bigger, so 12*6=72

A=60 inches by 72 inches

First painting perimeter: 10+10+12+12=44 inches

Second painting perimeter: 60+60+72+72=264 inches

264/44*100%=600%

Which undefined term is used to define an angle?<br><br> line<br> plane<br> point<br> ray
Afina-wow [57]

The Undefined term that is used to define an angle is a point.

<h2>Further Explanation: </h2><h3>Angle</h3>
  • An angle is defined as the union of two rays with a common endpoint.
  • The common end point is known as the vertex of the angle while the rays are known as the sides of the angle.
<h3>A ray  </h3>

It is a part of a line with one end point and proceeds on in one direction.

<h3>Naming of angles</h3>
  • Angles can be named in three different ways;
  1. Using three Capital letters such as ∠ PQR, or ∠BCD. The middle letter represents the vertex of the angle. Therefore, the angles above are read as "angle PQR" and angle BCD.
  2. Using the Vertex of the angle. For example, in the case of ∠PQR, can also be called angle Q, while ∠BCD can be called angle C.
  3. Angles can also be named by placing any number or symbol at the vertex in the interior of the angle. Such that angles can be called angle 1 or angle 3 , or angle 5, and so on.
  • Angles are measured using a tool known as a protractor
<h3>Measuring of an angle using a protractor</h3>
  • To measure the angle, the mid-point of a protractor is placed on the vertex of the angle.  
  • Then lining up one side of the angle with the zero line of the protractor.  
  • Then read the degrees where the other side crosses the number scale.

Keywords: Rays, angles, properties of angles, measurement of angles
