You can't answer the question without the other info. Can you get a better image?
It has zero solutions because -5a+5a= 0, and 9 does not equal zero, so there are no solutions.
Answer:
m∠2=31
m∠3=65
m∠1=?
Notice that measure of angle 2,3 and the angle that's next to angle 1 will form a triangle. Let's name the angle next to 1 to be x.
31+65+x = 180
96+x = 180
x = 180-96
x = 84
Now, you can easily find the m∠1.
84+m∠1 = 180 (REASON: Linear pair)
m∠1 = 180-84
m∠1 = 96
