Question

Write an equation to find the length of the side,x​

Answer 1

`\huge \: x = 18 \: ft`

Explanation:

to understand this

you need to know about

• trigonometry
• equation
• PEMDAS

TIPS AND FORMULAS:

• 
  `\sin( \theta) = (opp)/(hypo)`
• 
  `\sin( {30}^(o) ) = (1)/(2)`

given:

• opp:9
• 
  `\theta = {30}^(o)`

let's solve:

according to the question

`\sin( {30}^(o) ) = (9)/(x)`

`(1)/(2) = (9)/(x)`

`\huge \therefore \: x = 18`
