6, 9, 12, 15. All you need to find is multiples of 3.
ASA
Angle-Side-Angle
AAS is the same but the order in different.
SAS is a no because there are no two S.
Can't determine bah! You can determine.
PLEASE BRAINLIEST
By De Moivre's theorem,

We can stop here ...
# # #
... but we can also express these trig ratios in terms of square roots. Let
and let
. Then recall that



On the left,
so that

Since
, we're left with

because we know to expect
. Then from the Pythagorean identity, and knowing to expect
, we get

Both
and
are
-periodic, so that

and

so that the answer we left in trigonometric form above is equal to

Answer:
its A
Step-by-step explanation:
