Question

In the triangle below, b = _____. If necessary, round your answer to two decimal places.

Answer 1

use the sine formula to find c, then use the cosine formula to find b

Answer 2

\[\frac{a}{\sin(a)} = \frac{b}{\sin(b)} \rightarrow b=\frac{a}{\sin(a)} \times \sin(b)\]

Answer 3

you know the angle B its 180-34.5-29.8 = 115.7 degrees

Answer 4

now use the cosine rule to find b

Answer 5

\[c^2=a^2+b^2-2ab \cos(c)\]
gives
\[c^2=22^2+19.303^2-2\times22\times19,303\times \cos(115.7)\]
