An angle measures 81.2º more than the measure of its supplementary angle. what is the
measure of each angle?

Step-by-step explanation:

Supplementary angles add up to 180 degrees

Let x represent the smaller angle:

x + (x + 81.2) = 180

2x + 81.2 = 180

2x = 98.8

x = 49.4 degrees

therefore:

smaller angle = 49.4 degrees

larger angle = 49.4 + 81.2

= 130.86 degrees

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.

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
