Answer:
OC = 10.07 CM
BC = 9.73 cm
area triangle OAB = 97.98 cm^2
area of sector OADB = 150.05 cm^2
% of diagram that is shaded = 65%
Step-by-step explanation:
cos 44 = OC/14
0.71934(14) = OC = 10.07
sin 44 = BC/14
0.6947(14) = BC = 9.73
area of sector OADB = (88/380)(Pi)14^2) =150.05
area triangle OAB = (OC)(BC)(0.5)(2) = 97.98
% of diagram shaded = 97.98/150.05 = 0.65 = 65%
