The group hiked a total of 17.4 miles on the first day. on the second day that group heights a distance 12% more than the total distance hike on the first day. to the nearest tenth of a mile how many miles did the group hike on the second day?

-18

step-by-step explanation:

because mean value defines that total sum value over total number of set

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.
