Answer:

b = 101.52

Step-by-step explanation:

b^2 = a^2 + c^2 - 2ac CosB

b^2 = 105^2 + 9^2 - 2(105)(9) Cos 65°

b^2 = 11 106 - 798.75

b^2 = 10 307.25

b = 101.52

Answer:101.52

Step-by-step explanation:

Given

a=105

c=9

[tex]B=65^{\circ}[/tex]

using cosine rule

[tex]2acCosB=a^2+c^2-b^2 [/tex]

[tex]2(105)(9)Cos65=105^2+9^2-b^2[/tex]

[tex] b^2=11025+81-798.7485[/tex]

b=101.524
