line jk bisects mn at point j find mn if jm = 6 3/4 feet
since j is in the middle,
mn = mj+jn = 6 3/4 + 6 3/4 = ?
To find the length of MN, we need some additional information. Do you have any other measurements or angles?
To find the length of MN, we can use the information that line JK bisects MN at point J and that JM is equal to 6 3/4 feet.
When a line bisects another line, it divides it into two equal parts. So, if JM is equal to 6 3/4 feet, then JN (the other part of MN) will also be equal to 6 3/4 feet.
Therefore, to find the length of MN, we simply add JM and JN together:
MN = JM + JN = 6 3/4 feet + 6 3/4 feet.
To add these fractions, we need to have a common denominator. In this case, the denominator is 4, so we can write 6 3/4 as 6/4 + 3/4.
Adding the fractions:
MN = (6/4 + 3/4) feet
Simplifying the fractions by adding the numerators:
MN = 9/4 feet.
So, the length of MN is 9/4 feet, or 2 1/4 feet.
