arc ABC = 360 - 130 = 230

m<D  = 1/2(230 - 130)
m<D = 1/2(100) = 50

4th grade math. Help?!
viva [34]

Answer: Well... does it give you the approximate length or actual length of the butterfly? If so, you would take that length and multiply it by 5. That would give you the length of the 5 butterfly lined up together.

If it does not give you the approximate length or actual length, look up the length on google.  (Google Answer- Size: 2.5" - 4.0" range.)

Take that and multiply it by five to get the length of the 5 butterflies.
