Round to one decimal place as needed Solutionin the bluish t

Round to one decimal place as needed.)

in the bluish triangle, angle C = 90 + (90 - tan^-1(5/12)) = 180 - tan^-1(5/12) = 157.38^o

angle A = tan^-1(3/12) = 14.036^o

angle B = 180 - 157.38 - 14.036 = 8.584^o

now

BC/sinA = AC/sinB

BC = 19 x sin(14.036)/sin(8.584) = 30.87 ft = 30.9 ft

AB/sinC = AC/sinB

AB =19 x sin(157.38)/sin(8.584) = 48.96 ft = 49.0 ft
