Line jk bisects line mn at point j. find mn if jk = 6ft 3/4?
To find the length of line mn, we need to understand that a bisecting line divides another line into two equal parts. In this case, line jk bisects line mn at point j, which means line jk is dividing line mn into two equal parts.
Since line jk divides line mn into two equal parts, we can assume that the length of line jk is half the length of line mn.
Given that the length of line jk is 6ft 3/4, we need to find the length of line mn.
To find the length of line mn, we can double the length of line jk:
Length of mn = 2 * Length of jk
Now let's calculate it:
First, convert the length of line jk to a proper fraction:
6ft 3/4 = 6 + 3/4 = 24/4 + 3/4 = 27/4
Next, multiply the length of jk by 2 to find the length of mn:
Length of mn = 2 * (27/4)
To multiply a fraction by a whole number, we simply multiply the numerator by the whole number and keep the denominator the same:
Length of mn = (2 * 27) / 4 = 54/4
Finally, simplify the fraction:
Length of mn = 13 and 1/2 feet
Therefore, the length of line mn is 13 feet and 1/2 foot.
