56.9,

Step-by-step explanation:

Given:

a = 36, c = 48, ∠A = 39°

∠B1 is larger than ∠B2

Find attached the diagram.

We would apply sine rule to find ∠C

a/sinA = c/sinC

36/sin39° = 48/sinC

36sinC = 48sin39

sinC = 48sin39/36 = 48(0.6293)/36

sin C = 0.8391

C = arcsin(0.8391)

C= 57.045

∠C1 = C = 57.0° (1 decimal place)

For sine rule, angles which give same value are x and (180-x)

If C= x = 57.0°

180-x = 180 - 57.0° = 123°

∠C2 = 123.0°

sin57° = sin123° = 0.8387

∠A + ∠B + ∠C = 180° (sum of angles I'm a triangle)

39.0 + ∠B +57.0 = 180°

∠B = 180-(39+57)

∠B = 84.0°

∠B1 = 84.0°

∠B2 = 180-∠B1 = 180°-84.0°

∠B2 = 96.0°

∠B1 is smaller than ∠B2

b/sinB = c/sinC

b1/sinB1 = c1/sinC1

b/sin84 = 48/sin57

b = 48sin84/sin57

b = 56.9

is only a line? i think so
