Answer:
90 Minutes
Step-by-step explanation:
If he took 27 minutes to do 30% of his homework, then we can reverse the operation to find the total amount
30% is the same as 0.3, therefore you divide 27 by 0.3 because the 100% is 1, so by dividing you'll get the 100%.
This is a unit multiplier of sorts
1,900,000 x 45/30
Simplify
1,900,000 x 3/2
2,850,000
N-2,n and n+2;n-3,n and n+3,n-4,n and n+4....

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
