PIN is rotated -270 degrees about the origin

you would have to sell 24 bracelets.

step-by-step explanation:

84/3.5 = 24

i think the length is 12 and the width is 17

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.

they would have to work 32 hours.
