Question

Eddie solved for the length of side c in △CBD using the Law of Cosines formula,

Answer 1

Answer:

b^2= a^2+ c^2 -2acsin B

Step-by-step explanation:

In ΔABC, It is given that AB= c, AC=b and CB= a,

In order to find side length of b, she can use the Law of sines i.e

b^2= a^2+c^2-2ac sin B

by substituting the values of side lengths of a and c and sin angle B.

Answer 2

B^2 = a^2 + c^2 - 2ac sin B

is the answer
