Please help with questions 4,5 and 6!

Step-by-step explanation:

4) ∠CTB , ∠PTA are vertical angles

If sum of two angles add up to 90, then they are Complementary angles.

If sum of two angles add up to 180, then they are Supplementary angles.

∠FTA and ∠ATR are supplementary angles

5) ( 1 , 2 )  & (3 , 6)

             = (2 , 4)

6) Distance =

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
