$$ 30 points$$ david uses drawing software to rotate the regular hexagon about its center. through which angle measures can he rotate the hexagon to map it onto itself?

60°, 120°, 180°, 240°, 300° and 360°

Step-by-step explanation:

We know that  360° is a full rotation and a regular hexagon has 6 angles. So, they will map onto itself every 60°.

degrees.

Hence, we will take the multiples of 60 in the range:

degrees

So, we get the following angles:

60°, 120°, 180°, 240°, 300° and 360°.

18a

step-by-step explanation:

simply because it is. it's the highest common factor

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
