Answer:
11. 16x +(9x+5)= 180
25x + 5 = 180
25x= 175
x= 7
If x is 7, then the top value is equal to the bottm one becuase they are vertical angles.
112 + 4y= 180
4y = 68
y= 17
Step-by-step explanation:
12. 6x - 11 + 2x - 9= 180
8x - 20= 180
8x= 200
x= 25
6(25) - 11= 139
20y + 19 = 139
20y = 120
y=6

<u>Answer-</u>
An angle is labeled with either one capital letter or three capital letters
<u>Solution-</u>
<em>Point-</em>
As a point is 0 dimensional, so you just need 1 point to define a point.
<em>Line- </em>
As a line is 1 dimensional,so you need 2 points to define a line.
<em>Plane-</em>
A plane is 2 0r 3 dimensional, so you need 3 points to define a plane.
<em>Angle-</em>
An angle measures the amount of turn. An angles is labeled with a single letter at the vertex, as long as it is perfectly clear that there is only one angle at this vertex. Otherwise, it is named according to the intersecting lines with 3 letters.
The slope intercept is equal to the rise/run.
So lets say to get from one point to the other, you go down 2 units and go right 3 units.
Since you went down it is a -2. If you had gone up 2 units, then it would be a positive 2.
Since you went to the right, it is a positive 3. If you had gone left 3 units, then it would be -3.
-2/3
