It would be better if you've attached the figure its angle I should calculate. But I'll help you with some advice. You can find application in the internet that will calculate any angle by different ways. Just search your question, it will be first link
Use the cosine rule.
c=AB=7
b=AC=8
a=BC=3
a^2=b^2+c^2-2bc(cos(A))
=>
cos(A)=(b^2+c^2-a^2)/(2bc)
=(7^2+8^2-3^2)/(2*7*8)
=13/14
=0.9286
Answer:
1713 milliliters
Step-by-step explanation:
1 liter is 1000 milliliters, so 2 liters is equal to 2000 milliliters.
2000 mL - 287 mL = 1713 mL
So 1713 mL are left.
Answer: bigger number is 48 and smaller number is 36
Step-by-step explanation:
Let y be the yield of bushels of wheat in comparison to the amount of rainfall
Let x be the amount of rainfall that occurs (in inches)
If the linear regression equation is y = 47.3 + 0.78x, then per inch of rainfall will yield an addition 0.78 bushels (plugging into x the additional inches of rainfall).
Therefore, on the first inch of rainfall, y = 48.08.
On the second inch of rainfall, y = 48.86.
And so on.
