3-1/2 - (-1-1/3) = 4-5/6
Step by step: I took one point and subtracted the second point to get the length of each segment. You could also look at the ruler and count from one point to the other.
Remember when you subtract a negative, the two negatives become a positive

Answer:
Step-by-step explanation:
Recall the formula nCr=n! {(n-r)!r!}
Here, n=9, r= 4
9C4=9! / {(9-4)! 4!
=9! / (5! 4)
= 362880 / (120* 24)
=126
Awnser is 126
Check the picture below.
so we have two parallel lines, notice, the 115° are corresponding angles and thus equal, the 65° and 55° angles are linear angles to 115° and 125° respectively.
that leaves us with a triangle with 65° and 55°, and since all interior angles in a triangle sum up to 180°, then the last angle must be 60°, which has a twin vertical angle across the junction.
since a full revolution or a full circle go-around is 360°, the other two twin vertical angles next to the green 60° angles must be 360° - 60° - 60° = 240°, and since they're twins, each takes half of 240°.
