Answer:

x ≈ 1051.368672

Step-by-step explanation for #3:

tan(\frac{x}{12}) =24          <em>Use tangent function because it relates to the opposite and adjacent sides of the triangle.</em>

<em />tan^{-1}(tan(\frac{x}{12}))=tan^{-1}(24)<em />

<em />\frac{x}{12} = tan^{-1}(24)<em />

<em />x = 12[tan^{-1}(24)]<em />

x ≈ 1051.368672
