Taylor is competing in a 30 kilometers race. she has already run 12.35 kilometers through a park and swam 3.75 kilometers. she will bike the rest of the way. how far does taylor need to bike to finish the race? 8.6 km13.9 km16.1 km17.65 km

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.
