Answer:
2 /√3 or 2√3 / 3.
Step-by-step explanation:
Referring to the 30-60-90 triangle: hypotenuse = 2 , smaller leg = 1 and longer leg = √3 and the shorter side is opposite the 30 degree angle.
So cos 30 = √3/2
Sec 30 = 1 / cos 30
= 2 /√3
or 2√3 / 3.
distributive because you are distributing the outside number into the parentheses
Well let's see. Your -gon has 35 vertexies. You use one of them
to start all the diagnals from. That leaves (35 - 1) = 34 others
that could be the other end of a diagnal.
So there must be 34 possible diagnals.
Hey there!
We know that since the triangle got smaller, it had to have shrunk. The answer will be a fraction, we can eliminate choice A and C.
We can use the x-axis as reference to figure out how much it was dilated.
J went from 8 to 4.
L went from 12 to 6.
K went from 4 to 2.
We know that the dilation was centered around the origin, so, we can assume that these numbers were not influenced by anything other than the dilation.
4 is half of 8, 6 is half of 12, and 2 is half of 4.
The correct answer is 1/2.
I hope this helps!
