What is the measure of Angle c? . 42° 48° 90° 180°

90 degrees.

Step-by-step explanation:

Well, to solve the question, you can visualize a circle with all the lines inside of it. A circle has 360 degrees. To get angle C, you would add up the rest of the angles, and subtract them from 360 degrees.

360 - (48 + 42 + 90 + 48 + 42) = 360 - (90 + 90 + 90) = 360 - 270 = 90.

So, Angle C is 90 degrees.

Hope this helps!

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

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.
