The measure of length DE if DF = 61 and EF = 18 is 43
From the question, we are given the following measurement:
DF = 61
EF = 18
Required:
DE
Using the expression to find the measure of DE
DE + EF = DF
Substitute the given values
DE + 18 = 61
Subtract 18 from both sides
DE + 18 - 18 = 61 - 18
DE = 43
Hence the measure of DE is 43
