Answer:
1/5
Step-by-step explanation:
The probability of drawing an almond cookie the first time is 3/6=1/2, since there are a total of 6 cookies and 3 of them are almond. However, the second time the chance is 2/5, since there are 5 cookies left and only two of them are almond. The equation to model this is therefore:

45 i think i dont know
Step-by-step explanation:
m
∠

=
x
holds true.
Complementary angles have a sum of
90
˚
. Thus, if
∠
1
and
∠
2
are complementary,
m
∠

=
90
Substitute the equivalent forms of these angle measurements
(

x
=
90
Solve algebraically.
