At a Fourth of July celebration, a rocket is launched into the air with an initial velocity of 256 feet per second. The height, h of the rocket in feet above sea level is modeled by the equation h(t) = -16t2 + 256t, where t is the time in seconds after the rocket is launched. Part A: What is the height of the rocket after 5 seconds?

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.

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
