A. Vertical angles.
Complementary angles are adjacent angles that add to equal 90 degrees.
Adjacent angles are angles that share a side (they are right next to each other).
Supplementary angles are adjacent angles that add to equal 180 degrees.
Thus the answer is A.
Hope this helps.

Length = 2x+4
Step-by-step explanation:
P=2W+2L
14x+8 =2(5x)+2L
14x+8=10x+2L
14x+8-10x=2L
4x+8=2L
(4x+8)/2=L
<u>2x+4=L</u>
(9 + 4i ) + ( 36 - 2i) is the equivalent complex number
Answer: 90 degrees
============================
Explanation:
Let x and y be the two angles. Because they are supplementary angles, this means x+y = 180. Also since we're told that the angle is its own supplement, we can say that y = x.
Consequently, we can replace y with x and solve for x like so:
x+y = 180
x+x = 180 .... y is replaced with x since y = x
2x = 180
2x/2 = 180/2
x = 90
This means y = 90 as well. As a check, note how
x+y = 90+90 = 180
which verifies our answer.
