Answer:
45 i think i dont know
Step-by-step explanation:
m
∠
2
=
x
holds true.
Complementary angles have a sum of
90
˚
. Thus, if
∠
1
and
∠
2
are complementary,
m
∠
1
+
m
∠
2
=
90
Substitute the equivalent forms of these angle measurements
(
x
,
x
)
.
x
+
x
=
90
Solve algebraically.
2
x
=
90
x
=
45
Each angle is
45
˚
.
You need to take away 4 degrees from 92.
"Take away" means subtraction.
92 - 4
The answer is option C.
She did 12 questions, and needs to do 36.
36 / 12 = 3, so it will take 3 times as long.
1 hour 20 minutes times 3 = 4 hours.
It will take her 4 hours.
