Can someone help me? I'll reward points and brainalist

I think it D for number 2 and b for number 3

Step-by-step explanation:

1) B. 2) A.

Step-by-step explanation:

For number 1, put 30 into the equation. (3•30-5). When solved, your answer is 85, the same as the top. They are vertical angles which makes the two equal.

For number 2, I tried to draw the triangles on paper and the one that wasn't possible was A. The side 6 would be too long to connect to 4 or 3.

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'.
