CB is congruent to QR x+9 is congruent to 20 2y-1 is congruent to y+8
anonymous
  • anonymous
@stupidinmath yes that's it, then you can solve the value of y now, just equate it.

its hard when idk the other side of the triangle :| like CB & QR
anonymous
  • anonymous
why bother CB and QR, you are just ask to solve the value of y, and you just said earlier that "2y-1 is congruent to y+8", from here you can solve y.

is y=9 correct?

2y-1 is congruent to y+8 means the length of both sides are the same in other words, you can say 2y-1 = y+8 add -y to both sides 2y - y -1 = y+ -y + 8 y + -y is 0 on the right side. 2 y's take away 1 y leaves 1 y on the left side 1y - 1 = 8 now add +1 to both sides y -1 +1= 8+1 y=9
