What is the value of: 8√3 sin 30°tan 60° - 3cos0° + 3 sin245° + 2cos230?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 12
8√3 sin300 tan600 - 3cos00 + 3sin2450 + 2cos2300
= [8√3 × (1/2) × √3] - (3 × 1) + 3(1/√2)2 + 2(√3/2)2
= 12 - 3 + 3(1/2) + 2(3/4)
= 12 - 3 + (3/2) + (3/2)
= 12 - 3 + 3
= 12
