Answer:
1) a 130° - (360 - (50×2)) /2
B 50° - opposite angles
2) a 25° - 90° - 65 = 25 °
B 270° - 360° - 90° = 270°
3) a ) 60° - 180° - 120° = 60° (there are 180° in a straight line)
B) 90° - 180°-90° = 90°

Answer:
-3x-24
Step-by-step explanation:
9x - 3(4x+8)
Distribute
9x - 12x - 24
Combine like terms
-3x -24
The order that will result in a final output of -31 when the first input is 0 is as follows; Third → Second → Fourth → First
<h3>How to find the order?</h3>
First gives;
y = -2·x + 34 = 18
Second gives;
y = -x/3 - 10 = -38/3
Third gives;
= -24
Fourth gives;
y = (x - 2)² = 36
We have after several iterations;
Third gives,
= -24
Next we input into the second to get,
y = -(-24)/3 - 10 = 24/3 - 10 = 8 - 10 = -2
Next we input into the fourth to get,
y = ((-2) - 2)² = (-4)² = 16
Next we input into the first to get,
y = -2×16 + 34 = -32 + 34 = 2
Which gives the order as follows;
Third → Second → Fourth → First
