Answer:
ok I would give answer that is 85.5mi^2
Answer:
C
Step-by-step explanation:
Coterminal angles are angles that have a common terminal side.
So, given an angle θ, its coterminal angles will always be ±360°. This can be repeated.
We have a 645° angle.
Therefore, all values of the equation:

Where <em>n</em> is an integer is coterminal with our original angle.
Letting <em>n</em> = 1 and using the negative case, we acquire:

Therefore, an angle measuring 285° is coterminal with a 645° angle.
None of the other options can be reached by adding/subtracting 360.
Therefore, our answer is C.
Answer: B = 73
Step-by-step explanation:
Since A = 17 degrees and there's already a right angle (90 degrees)
They add up to 107 degrees meaning the last angle is 73 because
the sum of interior angles add up to 180.
I'm sorry I couldn't find the other ones ( I don't have time )
but I'll give you a hint. You'll need to use Sine, Cosine, or Tangent
A is 6, a = 6
b = -1 - 7a
b = -1 - 7(6)
b = -1 - 42
b = -43
