Triangle abc has sides of length 45, 60, and 75. place a point d randomly and uniformly inside the triangle. what is the expected value of the sum of perpendicular distances from point d to the triangle's three sides?

idk

step-by-step explanation:

i don't know

w'x is 0.

hope it

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
