Question

Can you please help me with number 18? I am confused with it

Answer 1

Recall that in a right triangle we know that:

`\tan \theta=\frac{\text{opposite leg}}{adyacent\text{ leg}}.`

Therefore:

`\tan 29^(\circ)=(x)/(15).`

Multiplying the above equation by 15 we get:

`\begin{gathered} \tan 29^(\circ)*15=(x)/(15)*15, \\ x=15\tan 29^(\circ)\text{.} \end{gathered}`

Answer:

`x=15\tan 29^(\circ).`
