Explanation / Answer

C = 58deg20'min = 58.33 deg ; c = 33.4 ; b = 24.5

sin law : b/sinB = c/sinC

sinB = (24.5*sin58.33)/33.4 = 0.624

B1 = 38.63 deg = 38deg38 min ; B2 = 141.37 = 141 deg 22 min

A1 = 180 - 38.63-58.33 = 83.04 deg = 83 deg 2 min

A2 = 180 - 141.37 -58.33 = -ve angle .Not possible

So, only 1 triangle is possible with C =,58deg20'min ; B1 = 38deg38 min, A1= 83 deg 2 min

a/sinA = b/sinB

a = sin83.04*24.5/sin38.63 = 38.96
