so the lake is in sections of 4
take 4 times it by 7
answer is 28 feet
to check your answer 28/32 simplified is 7/8
Focus on triangles DFC and DFE:
- They are both right triangles because DF is perpendicular to EC
- DC=DE
- DF is a common side
So, the two triangles are congruent. It follows that CF=FE, and in particular

And since x=3, the length of EF is
