Answer:

240.6 feet

Explanation:

to understand this

you need to know about:

  • trigonometry
  • PEMDAS

let's solve:

to find x we will use cos function


\quad \: \cos( \theta) = (adj)/(hypo)

substitute the value of
\theta and adj:


\quad \: \cos( {67}^( \circ) ) = (94)/(x)

cross multiplication:


\quad \: x\cos(67^(\circ))= 94

divide both sides by cos(67°) :


\quad \: \frac{x \cos( {67}^( \circ) ) }{ \cos( {67}^( \circ) ) } = \frac{94}{ \cos( {67}^( \circ) ) } \\ \therefore \: x = 240.6
