Answer:
CE = 25
Explanation:
if a line is parallel to a side of a triangle and it intersects the other two sides, then id divides those sides proportionally, that is
=
( substitute values )
=
=
( cross- multiply )
2CE = 5(35 - CE)
2CE = 175 - 5CE ( add 5CE to both sides )
7CE = 175 ( divide both sides by 7 )
CE = 25
