Answer: The river is 148.3 feet wide.
Step-by-step explanation:
Alright, lets get started.
Please refer the diagram I have attached.
The triangle formed is a right triangle.
Using SOH CAH TOA
Multiplying 100 in both sides
Rounding to the one decimal place
Hence river is 148.3 feet wide. .............. Answer
Hope it will help :)
For a better understanding of the solution given here please find the attached file which has the relevant diagram.
To answer this question we will have to make use of <u>the Isosceles Triangle Theorem</u> which states that the perpendicular bisector of the base of an isosceles triangle is also the angle bisector of the vertex angle. Thus, as a corollary we know that is EF is the angle bisector of the vertex angle ∠E, then, EF is the perpendicular bisector of the of the base DK.
Please follow the diagram of a complete understanding of the logic and the solution.
As EF is the angle bisector as given in the question, thus we will have:
.
Also, from the Theorem we know that KF will be half of DK and thus, KF will be: centimeters.
Likewise, from the same theorem we have:
