Find the value of:
[tan260° + 3 cos230° — 2 sec230° — cot260°] ÷ [sin 60° cos 30° — cos 60° sin 30°]
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. .
[tan260° + 3 cos230° — 2 sec230° — cot260°] ÷ [sin 60° cos 30° — cos 60° sin 30°]
We will put the value of trigonometric functions from the trigonometry table
⇒ [ × (√3)2 + 3 ()2 — 2 × ()2 — × ()2] ÷ [() × () — × ]
⇒ [ × 3 + 3 × — 2 × — × ] ÷ [ — ]
⇒ [4 + — — ] ÷ []
⇒ [4 + — — ] ÷ []
⇒ (48 + 27 - 32 - 3)/12 × 2
⇒ (48 + 27 - 32 - 3)/6
⇒ = =
