Question

Use the Law of Cosines to solve the triangle to find the length of b, if A= 48degrees, b = 3, and c = 14.

Answer 1

\[a^2=b^2+c^2-2bc \cos A\]
\[a^2=3^2+14^2-2(3)(14) \cos 48\]
\[a = 12.20\]

Answer 2

i agree with matt

Answer 3

I'm assuming you wanted to find the length of a, not b.

Answer 4

I agree with DHASHNI :P

Answer 5

Haha yeah I did. Thanks you guys

Answer 6

@matt: you foun the length of 'b' and labelled it as 'a'
your answer is correct

Answer 7

No dakid91 said b twice in the question, but since angle A and side b were given, I assumed we were going for side a haha

Answer 8

LOL
