Answer fast : | logan is a land surveyor. he wants to determine d, the distance across a lake that cannot be directly measured. he draws this diagram to him. what is the approximate distance across the lake, to the nearest tenth of a kilometer? 5.7 km 6.3 km 11.4 km 16.0 km

any options?

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
