Use a special right triangle to write cos 30º exactly

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.

wait nvm i know the correct answer now its 100%   81 square feet

~batmans wife dun dun

answer is (b.

164 ft2)

a base  

18

b base  

7

h height
