Answer:
63*
Step-by-step explanation:
The first thing you need to do is find the value of x. What I did for this was trial and error. I tried a number, and if it was too big, I tried a smaller one. If you add up all of the angles, it should equal up to 180*, so I kept on doing this until I added up to 180.
The answer I got was x=8, so I plugged this into the equation for A and solved. 9x8 is 72, and 72-9 is 63.
Therefore, 63 is the correct answer.
Algebraically, that would be 5n - 11 = 24

If the yearbook club had 1/2 the participants attend the meeting, than all of them would be represented by 18 x 2, or 36 (since two halves make a whole)
In an isoceles triangle two angles are equal
if u take the coordinates and apply it in the graph it makes and isoceles triangle
as the y-axis is zero two of the ends will be level and x-axis is equal on both sides of the origin so (0,4) will be the third non equal angle
