Is anyone able to help with this? It relates to symmetry. Thanks ahead if you can! You are told that a particular finite 2D figure has exactly 24 symmetries (including the trivial symmetry).

-List all the possible symmetry types that the figure might be:

Suppose that the figure has at least one reflectional symmetry.
-What is the symmetry type of the figure?:

Suppose that the figure has no reflectional symmetries.
-What is the symmetry type of the figure?:

what's the question?

step-by-step explanation:

there is no question.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation

he answer is x=1x3 because x=1 to x=3
