To find: The values of BE and CF .
Answer to Problem 14WE
The values of BE and CF are 14 and 21 respectively.
Explanation of Solution
Given:
The
Calculation:
Consider a triangle TBE ,
AD is the midsegment of the triangle TBE .
According to the midsegment theorem, the length of midsegment is half of base of triangle.
Hence,
Consider a trapezoid CFDA ,
Thus, BF is the midsegment of the trapezoid CFDA .
According to the midsegment theorem, the length of midsegment is half of sum of parallel sides of trapezoid.
Hence,
Thus, the values of BE and CF are 14 and 21 respectively.
