Answer:
A
Step-by-step explanation:
1 over 10x10x10 is basically, 10 to the power of 3. 10x10 is 100, and 100x10 is 1000. An easy way to do this. Since we have 3 tens, we start with 10, then add a 0, then add another 0. Gives you 1000.
The sum of the inner angles of any triangle is always 180°, i.e. you have

In the particular case of an equilater triangle, all three angles are the same, so

and the expression becomes

which implies 
So, if you rotate the triangle with respect to its center by 60 degrees, the triangle will map into itself. In particular, if you want point A to be mapped into point B, you have to perform a counter clockwise rotation of 60 degrees with respect to the center of the triangle.
Of course, this is equivalent to a clockwise rotation of 120 degrees.
Finally, both solutions admit periodicity: a rotation of 60+k360 degrees has the same effect of a rotation of 60 degrees, and the same goes for the 120 one (actually, this is obvisly true for any rotation!)
Answer: I think it’s A if I am incorrect I am very sorry
Step-by-step explanation:
Answer:
B) x - y = 0
Step-by-step explanation:
The equation for the line shown is y=x. This can be written in general form by subtracting y:
x - y = 0
_____
General form for the equation of a line is ...
ax +by +c = 0
where a, b, c are preferred to be mutually prime integers and a ≥ 0. If a = 0, then b ≥ 0.
