Then they are supplementary angles which mean both of those angles add up to 180°
Answer:
86°
Step-by-step explanation:
(a+c)/2=86
in this case, a=c
so,
2c/2=86
or, c=86
Answer:
C is the most suspicious set.
Step-by-step explanation:
We would expect that B wins 4/5 * 30 = 24 games.
In set A, B wins 23 games.
In B, B wins 24 games.
In C, B wins 15 games.
In D, B wins 25 games.
So result C is very suspicious.

now, a line perpendicular to that one, will have a "negative reciprocal" slope, thus
