I only (sort of) know 3 and 4
3. Andle 1 is an example of an angle bigger than

I don't know what you call it.
4. If you have a straight line, both angles (or more) added up need to be

so if angle 1 is 129, 180-129=51
angle 2 is

If 1 is what is the relationship between the two angles, then maybe the answer is that they both added up need to be 180 degress (?)
And 2 is probably the same as 3 but with angle 2, angle two is an example of an angle smaller than 90 degrees

Answer:
1. f(x,y) = (x, -y) 2. f(x,y) = (-x,y).
Step-by-step explanation:
I hope that helps
Let x = number of long sleeve shirts
Let y = number of short sleeve shirts
x + y = 200
x/2 + y/3 = 80
Now solve this pair of simultaneous equations to find x and y.
