5. ∠1 and ∠2
6. ∠2 and ∠3
7. ∠1 and ∠3
Because the exterior angle of a triangle is equal to the remote interior angles we can set up the following equations:

and the median (middle number) is 5 <==
because 2 dots above the 3 means u have 2 threes....and 1 dot above the 4 means there is 1 four..and so on
