HEEELLLPPP A triangle was dilated by a scale factor of 2. If cos a° = three fifths and segment FD measures 6 units, how long is segment DE?

triangle DEF in which angle F is a right angle, angle D measures a degrees, and angle E measures b degrees

segment DE = 3.6 units

segment DE = 8 units

segment DE = 10 units

segment DE = 12.4 units

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
