Does this have rotational symmetry, no, 180, 90, 30?

b: 1 is the final answeer! : )

ok

step-by-step explanation:

thus, the first answer choice, y = sec x, is the correct one

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !
