To estimate the length of the lake, caleb starts at one end of the lake and walk 95m. he then turns a 60° angle and walks on a new path and walks 8m more then arrives at the other end of the lake. approximately how long is the lake?

Length of the lake is 97.30 m

Step-by-step explanation:

We have given Caleb starts at one end of the lake and walk 95 m

So

And then he turns at an angle of 60°

So and then again walk 8 m

So

We have to fond the total length of the lake , that is d

Total length of the lake is given by

So length of the lake is 97.30 m

-2x-4

step-by-step explanation:

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
