Answer:
c = sqrt 13.4689 rounded to sqrt 13.5 = 3.5
Step-by-step explanation:
maybe A+ B totals sqrt 13 = 3.60555128 if so they have rounded down for c to = 9 then 6 + 8 added on ay = sqrt 6+ 8 = sqrt 14 = sq rt 3.74165739 in all effect if triangular = average of a= b = 3.67^2 = 13.4689 then through Pythagoras c = sqrt 13.4689 rounded to sqrt 13.5 = 3.5
It's the letter C............
