Question

Find ad please help aghhhh due today

Answer 1

AD = 6m

Explanation:

Sin(30) = AD / 12

Sin(30) * 12 = AD

6 = AD

Hope this helps!

Answer 2

Question :-

Find AD.

`\sf a. \: 2√(3) \: m`

`\sf b. \: 3 √(3) \: m`

`\sf c. \: 6 \: m`

`\sf d. \: 6 √(3)`

____________________

Solution :-

Given Information :-

• ∠DCB = 30°
• ∠BDC = 90°
• ∠ABC = 90°
• BC = 12 m

To Find :-

• The Length of AD

Calculation :-

Here, Sin θ is 30°

Sin =
`\bf (perpendicular)/(hypotenuse)`

Here, θ is 30°

Substituting the values, We get,

∴ Sin ( 30 ) =
`\sf (AD)/(BC)`

Substituting the value of BC as 12, We get,

⇒ Sin ( 30 ) =
`\sf (AD)/(12)`

Transposing 12 to Left Hand Side, We get,

⇒ Sin ( 30 ) × 12 = AD

Calculating further, We get,

⇒ AD = 6 m

∴ AD = 6 m

Final Answer :-

The Length of AD is 6 m
