SAS because its is side angle side for both of them
One thing to remember about percent is that "%" means the same as "/100".
A) 25% = 25/100
B) (25/100)*(total pieces) = 20 pieces
Multiply by 100/25 = 4
.. total pieces = 4*(20 pieces) = 80 pieces
Answer: 80 pieces of paper
Segment addition postulate says
AB+BC=AC
assuming that A, B, C are in order, and assuming that those are the points,
legnth of AC=|A-C|=39 (|x| means absolute value of x)
A=2x-8
b=17x
AB=|A-B|=|2x-8-17x|=|-8-15x|
we are only given AB but not BC so this is not solvable unless you know BC
AB+BC=AC
BC=AC-AB
BC=39-|-8-15x|
that's as far as I can go since we don't know any more
The next point would be (5, 4).
