lara is setting up a convention room. she is expecting 240 attendees and can comfortably fit chairs in rows of 16. how many rows does she need to set up?

definitely a. the others have almost all data points on one side of the line.

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.

answer: 72: 111
