A triangle, RST, is reflected across the y-axis to form the triangle R'S'T' in the standard (x, y) coordinate plane; thus, R reflects to R'. The coordinates of point T are (j, k). What are the coordinates of point T'?

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.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
