Solution

) a = 76,    b = 105,    A = 26°

a/sinA = b/sinB

sinB = 105*sin26/76 = 0.605

B1 = 37.3 deg ; B2 = 180 - 37.27 = 142.7 deg

C1 = 180 -A - B1 = 116.7deg ; C2 = 180 -A - B2 = 11.3 deg

So, B1 = 37.3 deg ; C1 = 116.7 deg ; B2 = 142.7 deg ; C2 = 11.3 deg

c/sinC = a/sinA

c1 = 154.9 ; c2 = 34

2) b = 47,    c = 41,    C = 37°

c/sinC = b/sinB

sinB = 47*sin37/41 = 0.689 ;

B1= 43.6 deg ; B2 = 180 - B1 = 136.4 deg

A1 = 180 - C - B1 = 99.4 deg ; A2 = 180 - C - B2 = 6.6 deg

a1/sinA1 = c/sinC ; a1 = sin99.4*41/sin37 = 67.2

a2 = 7.83

3) a = 104,    b = 89,    A = 136°

b/sinB = a/sinA

sinB = b*sinA/a = 0.594

B1 = 36.5 deg ; B2 = 180 - B1 = 143.5 deg

C1 = 180 - 136 - 36.5 = 7.5 deg ;C2 = 180 - 143.5 - 136 = DNE

So, B = 36.5 deg ; C = 7.5 deg

c/sinC = a/sinA

c = 19.54
