A yacht leaves port P and travels 34km due north to an island I. At I, the yacht turns on a bearing of 054° from I and travels a further 48km until it reaches marker buoy B. At B, the yacht turns again and travels back in a straight line to P. Calculate the total distance travelled by the yacht, to the nearest kilometre.

it is probably the graph on the bottom right.

a negative exponent is translated as follows:

so, we have

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

something over 10 so ? /10
