Rosa y María parten del mismo punto siguiendo cada una trayectoria recta, formando entre las mismas un ángulo de 35°10’. Si Rosa camina 300 m y María 800 m, ahora están a una distancia una de la otra de: .581,04 m

.518,04 m

.397 m

.970,77 m

​

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

answer: i think you should do the math and pay attention in class : )

step-by-step explanation:

that is truly what   think but if i get the answer i will

hope this !
