I really really need help with this question /:
first one, the two triangles are similar with ratio 5:3 a/b = 3/5 b/(8+a) = 3/5 second one, they are similar too x/ (x+5) = (x-2)/(2x-1) solves those
Oh, I solved the second one! :D I don't understand the equation you gave for the first... I just do the second equation- b/(8+a) = 3/5?
which one did u do? a/b = 3/5 5a = 3b b/(8+a) = 3/5 5b = 24 + 3a 5a = 3b * 5 25 a = 15 b 24 + 3a = 5b * 3 72 + 9a = 15b -72 + 16a = 0 a = 4.5 substitute back in to find b
I did, a couple of times but I'm no getting any of the multiple choice. The closest I'm getting to is the third one, c.... Is it C?
a = 4.5 = 9/2 5a = 3b 5 (9/2) = 3b 15/2 = b
Thank you for your help
