Daniel, ryan, and sam are friends. daniel is ryan's brother. ryan is sam's brother. sam is not daniel's brother. how is this possible?

So we know that the three boys are friends – Sam, Ryan and Daniel.

We also know that Daniel is Ryan’s brother and Ryan is Sam’s brother.

But the question here is why does Sam is not Daniel’s brother.

Because the answer here is Sam is a girl which makes her a sister of Daniel, not a brother.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
