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.

Answer:
x = ± 
Step-by-step explanation:
9x² - 4 = 0 ( add 4 to both sides )
9x² = 4 ( divide both sides by 9 )
x² =  ( take the square root of both sides )
 ( take the square root of both sides )
x = ±  = ±
 = ±  = ±
 = ±
