Bruce's speed when swimming in still water is 5 meters/second. he is swimming in a direction 25° east of north. the current is moving 3.5 meters/second at an angle of 60° west of south. identify bruce's vector, the current's vector, and the vector representing bruce's actual motion.

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
