Answer:
84 degrees
Step-by-step explanation:
Applying the Cosine Rule (Choice 2 is the correct one) :-
12^2 = 11^2 + 6^2 - 2*11*6 cos Y
144 = 121 + 36 - 132 cos Y
cos Y = (121 + 36 - 144) / 132
cos Y = 0.09848
Y = 84.3 degrees
B, short explanation remember the sets are set up like (x,y) in a set there should be no matching x points so if it matches it's not a function :)
long explanation: these are (x,y) sets {(0,3), (3,0), (0,4), (4,0)} the first choice shows that there are two X solutions <span>if they are equal to 0 (0,3) (0,4) so this cant be a function.
second choice</span><span> {(0,2), (2,0), (4,6), (6,4)} does not have two X solutions so this is a function
third choice</span>{(2,6), (3,6), (4,6), (2,0)} has two X solutions if x is equal to 2
and the last choice <span>{(6,2), (2,0), (4,6), (6,4)} has two X solutions if x is equal to 6
hope i helped! if i did please give me brainlest :)

Answer:
n=-2
Step-by-step explanation:
Because when you are looking at the numbers they drop by two, so the answer must be decreasing by n= -2.
