⚠️URGENT⚠️ What is the relationship between Za and Zb?
A vertical angle
B complementary angle
C supplementary angle
D none of the above

The angles a and b are complementary in the fact that they will add up to 90 degrees.

B. complementary angles

Step-by-step explanation:

Vertical angles:

Two angles opposite of each other when 2 straight lines intersect. These are always congruent.

Complementary angles:

Two or more angles that add up to 90 degrees.

Supplementary angles:

Two or more angles that add up to 180 degrees.

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
