We are given
are odd which means:


We can tell if a function,
, is even if
.
We can tell if a function,
, is odd if
.
So let's test your I,II,III.
We will be replacing x with -x to find out.
I.





So
is odd.
II






So
is odd.
III





So
is even.
So I and II are odd and III is even.
C. is the answer.
Answer:
mA = 69 degrees
Step-by-step explanation:
A complementary angle has a measure of 90 degrees.
(2x + 27) + (2x - 21) = 90
Simplify
4x + 6 = 90
-6
4x = 84
/4
x = 21
mA: 2(21) + 27 = 69
2 3 5 7 9 11 13 15 17 19 21 it goes up by 2

<span> the diagonals bisect each other, then 1/2 the longer diagonal is 13
So, (13/34) represents 1/2 of the angle that the larger diagonal bisects. The angle would be approximately 2*67, or 134°</span>
