Question

Write an equation that could be used to find the value of b.

Answer 1

A. 2^2 = b^2 + 3^2 – 2(b)(3)(cos 38°)

B. 38^2 = 2^2 + 3^2 – 2(2)(3)(cos b°)

C. 3^2 = 2^2 + b^2 – 2(2)(b)(cos 38°)

D. b^2 = 2^2 + 3^2 – 2(2)(3)(cos 38°)

Answer 2

@Loser66 I got A. Is that correct?

Answer 3

hihihi.. your question is about b, b should be on the left side, right?

Answer 4

oh yeah!

Answer 5

so it's D.

Answer 6

yup

Answer 7

but it's asking for an equation that could be used to find b...does b have to be on the left side?

Answer 8

"equation" is something has the equal sign "=" like a = b....
"find b" , then b should be what we need, it should be b =.....

Answer 9

Oh ok. Thank you for explaining. :)
