Question

If I have to find the length of b, which angle should I use?

Answer 1

For b I should use tangent as it's perp/base I have b as the perp and 10 as the base. Right?

Answer 2

yes but i think the data is insufficient

Answer 3

\[\tan \theta=\frac{b}{10}\]
\[b=10\tan \theta\]

Answer 4

the value of theta is to be known that is the reason i mentioned data is insufficient

Answer 5

The question only asks for the ration, which ratio should I use? cos, sin, tan, or sec?

Answer 6

ratio**
