If DeltaABC is right - angle at B, AB = ...

If `Delta`ABC is right - angle at B, AB = 6 units `angle = 30^@` then AC is equal to

A

10 unit / 10 युनिट

B

12 unit / 12 युनिट

C

15 unit / 15 युनिट

D

8 unit / 8 युनिट

Verified by Experts

The correct Answer is:

B

`sin 30^(@) =(AB)/(AC)`
`rArr (1)/(2)=(6)/(AC)`
`rArr AC = 12` unit
