x=13 because you put all of them in an equation and set them equal to 180 bc that is how many degrees are in a triangle so it would be 6x+19+5x-15+3x-6=180 and then you solve the equation so it would be 14x-2=180 then you would add to to both side which would cancel out on the left and make 182 on the right then divide 182 by 14 and you get 13.
2*13 equals 26
that is another problem
He started at 0, then he went up to a elevation of 14 m, then went down to 19m so it is 14-19 which =
-5 meters
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;
- 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.
- 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.
- 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.
