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.
1. Solution: X= -2.5
Steps:
0= 2x +5
-2x=5
X= -5/4
2. Solution: x=3
Steps:
0=(x-3)2
(X-3)2 = 0
X-3=0
X=3
