Below, enter your answers so that A_1 is smaller than A_2.) b = 125, c = 163, B = 43 degree A_1 = degree A_2 = degree C_1 = degree C_2 = degree a_1 = a_2 = Solve triangle ABC. (If an answer does not exist, enter DNE. Round your answers to one decimal place.) a = 51, b = 64, A = 56 degree B = degree C = degree c =
Solution
9) given b =125,c=163,B=43o
by law of sines a/sinA=b/sinB=c/sinC
b/sinB=c/sinC
125/sin43o=163/sinC
sinC=(163/125)sin43o
C1=62.8o,C2=117.2o
A1+B+C1=180o
A1+43o+62.8o=180o
A1=74.2o
A2+B+C2=180o
A2+43o+117.2o=180o
A2=19.8o
a1/sinA1=b/sinB
a1/sin74.2o=125/sin43o
a1=125sin74.2o/sin43o
a1=176.4
a2/sinA2=b/sinB
a2/sin19.8o=125/sin43o
a2=125sin19.8o/sin43o
a2=62.1
