Math help please?
Hey we just had a test on this yesterday in geomerty.





Number one is 9.


the midsegment is half the paralle side's length





Number two is 4.


you just do (2)4x-1 = 30


since the midseg. is half the parall side





Number three is 3.


you just do (2)4x-2=7x-1


same as numbers two.





Number four is 10.


since AD is 5, and DC is congruent to AD,


you just add them up.
