Answer:
[tex] \huge \: x = 18 \: ft[/tex]
Step-by-step explanation:
to understand this
you need to know about
- trigonometry
- equation
- PEMDAS
TIPS AND FORMULAS:
- [tex] \sin( \theta) = \frac{opp}{hypo} [/tex]
- [tex] \sin( {30}^{o} ) = \frac{1}{2} [/tex]
given:
- opp:9
- [tex] \theta = {30}^{o} [/tex]
let's solve:
according to the question
[tex] \sin( {30}^{o} ) = \frac{9}{x} [/tex]
[tex] \frac{1}{2} = \frac{9}{x} [/tex]
[tex] \huge \therefore \: x = 18[/tex]
