Answer:
for this problem we use the sine function
[tex] \sin(x) = \frac{opp}{hyp} \\ \sin(38 ) = \frac{x}{100} [/tex]
multiply both sides of the equation by 100
[tex]100 \sin(38) = \frac{100x}{100} [/tex]
100 cancels on the right hand side of the equation
[tex]100 \sin(38) = x \\ x = 61.566\:ft[/tex]
