Question

Can anyone help me!!

Answer 1

Explanation:

by writing the formula of tan(30°), you'll get the answer.

Let's write it :

tan(x)=
`(opposite)/(adjacent\\)`

we have a 30° angle so x=30° :

tan(30°)=
`(AB)/(AC) = (AB)/(6) =(1)/(√(3) )`

⇒ √3 * AB = 6 ⇒ AB=
`(6)/(√(3) )`≅ 3.46

Answer 2

AC : AB = tan30
6 : AB = tan30
0.58AB = 6
AB ≈ 10.3
