60 milligrams
Step-by-step explanation:
just cross multiply! percentages are just fractions of 100. so you can say that 
multiple 75 by x and 45 by 100 and you get
4500=75x
divide both sides by 75 and you get 60
Answer:
If you need what x equals its -16
Answer: 400,000

I hope this helps!! :)
By pythagoreans' theorem,
Longer edge
= √(2² + 6²)
= √40
∴ The length of the longer edge is the square root of 40 feet.
Shorter edge
= √(1² + 3²)
= √10
Area = L × B
= √40 × √10
= 20 feet²
360 / 12 = 30
So, it's 30 degrees.
Incidentally, a 12 sided polygon is called a dodecagon.
