Answer:
C = 40 degree
AB = 5.785 = 55.79, = 5.8 = 6 (4,3,2,1 significant figures)
BC = 11.748 = 11.75 = 11.7=12 (4,3,2,1 significant figures
Step-by-step explanation:
ASA Angle Side Angle (given)
90-50=40 degree as all angles within triangle add up to 180 degree
C = 40 degree
AC (given = 9
AB = A/H = 9xcos(50) = 5.8 measure
BC = O/H = 9 / sin (50) = 11.7 measure
