b
Step-by-step explanation:
im not 100% sure sorry
Answer:
31 i think
155.3 divided by 5 is equal to 31
Answer:
B
Step-by-step explanation:
well by rotating ΔABC by 60*(degrees) about A , such that in ΔA'B'C,B =C'
you can see that ΔAPP' is equilateral side length 1, meaning that <APP' =60*
you can also see that ΔCPP' is a 30- 60- 90 right angle also meaning that <CPP' =60* now,by adding the two together you see that < ACP =120* now you can also use the law of cosins and soooo
s2=(AP)2+(CP)2-2(AP)(CP)cos120*
s2=1+4-2(1)(2)cos120*
s2=5-4 (-1over2)
s=
7
so b is your answer hope this helped
First of all, look at the figure, The ABC orientation is changed from clockwise to counterclockwise, so an odd number of reflections are involved.
Second, look at the answer choices. Right away, you notice that the last choice (E) involves two reflections. That cannot be the transformation you see. Since that is what the question is asking for, the appropriate choice for the transformation NOT done is ...
... E. reflection across the x-axis followed by a reflection across the y-axis
_____
I have to admit, I went through each of the choices to see if it would work to produce the image you see. All choices except E will do that. All that work turned out to be unnecessary.
