If △ABC is right angled at B, AB = 12 cm and ∠CAB = 60°, determine the length of BC.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 12√3 cm
Given that
If △ABC is right angled at B, AB = 12 cm and ∠CAB = 60º
The length of BC = AB × tan 60º = 12 × √3 = 12√3 cm
