Draw a diagram, the base angles of an isosceles triangle are the same and all angles of a triangle add to 180 degrees.
All the angles in a triangle add to 180 and in an isosceles triangle 2 of the angles are the same. So JKI and JIK are the same number of degrees. So 180-J= JKI+JIK.
The probability that A will win is 2/3 and that B will win is 1/3 so if A wins three times in a row, 2/3*2/3*2/3=8/27.
Pretty sure there is a messege board on aops you can use.
There is a message board... don't post the aops writing problems here please...
26*25*24*23=358800 without any uppercase letters and no repeated letters and 52*51*50*49= with uppercase letters
What happens if there is an odd number of ppl?
Plug g(x) into the x in f(x)
Parallel lines have the same slope so the only change would be the y intercept. It goes up and right one so to get to x=0 we add 2 so the y intercept is (0, -3) and the equation is y=x-3
Part of an aops problem... use the msg board... week 19 right?
