Answer:
The Triangle Sum Theorem is also called the Triangle Angle Sum Theorem or Angle Sum Theorem. It says that all the angles <em>inside</em> a triangle add up to 180°.
---------------------------------------------------------------------------------
Take a look at the picture attached. It has a "formula": ∠a+∠b+∠c=180°
Use this as it will help you a lot. You plug in the info you already know (it doesn't matter which angle is a,b,c) and solve for the missing one. :)
Ask in the comments below if you are not sure about something.
I hope that helps you! :D
Answer:
D. $56
Step-by-step explanation:
Sandra's taxable income is $39,250.
That amount works for range 2 ($39,250 - $39,300), so her tax is $5,944.
Sandra paid $6,000 in FWT (federal withholding tax), which is greater than $5,944, so we need the refund here.
Subtract 5,944 from 6,000 to get the refund.
6,000 - 5,944
We can go on ahead and just make this 100 - 44 (5,900 - 5,900 = 0).
100 - 44
Her refund is $56.
The correct answer are A. and B.
Good luck!!!
Points of inflections are zeroes of the second derivative. We have:
So, the second derivative equals zero if and only if
So, this is the only point of inflection of this function.
It is an isosceles triangle
