Frances used small, medium, and large cups to serve punch. she used 243 medium cups. she used 79 more medium cups than a large cups. she used 56 more small cups than large cups. how many small cups did frances use to serve punch?

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.

d. corresponding side lengths in similar triangles are proportional in length.
