Step-by-step explanation:
Using cosine rule,
f² = g² + e² - 2(g)(e)(cosF) = 6.7² + 5.9² - 2(6.7)(5.9)(cos70°)
= 52.6598 in²
Hence f = 7.3 in.
hmmm let's find the distance between B and C first off.

hmmm if BC is that much, then AB + AC = 7, since AB + AC + BC = 12 which is the perimeter, Check the picture below.
The answer for your question is that when h have 12 logs then you add 11 then you get 6 more it is 29
I don't get because you did not add a symbol between 110 and 7/16 so i can't tell you.
