Question

What is the length of DB?

2
2√3
√3
1.5

Answer 1

Answer:sq 3

Explanation:

Answer 2

`√(3)`

Explanation:

In ΔABC ∠C=90° , ∠A =30°

Let ∠B =
`\alpha`

∠A+∠B+∠C = 180°

⇒90° + 30° +
`\alpha`° =180°

⇒
`\alpha` =60°

Now, in ΔACD
`sin(30)=(CD)/(6)`
`=0.5`

CD =3

In ΔCDB
`tan(60)=(3)/(BD)`=
`√(3)`

BD =
`√(3)`
