The answer is 63 cm bc 30 60 90 triangles have a rule where the short leg is x longer is x√3 and the hypotenuse is x2
you can see this if you imagine the triangle as equilateral then cutting it in half
C. 10/x+8
The easy way to do it would be to take it one step at a time.
In order to add these fractions we have to make a common denominator.
1/5 can turn into 2/10 Its the same thing. And its easier to solve with.
now lets multiply.
× 
Now we add across
2 + 1 = 3
------------
10 + 10 = 10 ( When adding fractions like these the denominator stays the same)
So your answer is...

Good Luck! :)
Answer:
d. 94
Step-by-step explanation:
If business decreases 10%, it is 100% - 10% = 90% of normal.

if business is 94% of normal, it is not between these values, so is not a winter business statistic.
