Question

2√2 cos 45° × Cos 60° +2√3 Sin 30° × ton 60° - Cos 0°​

Answer 1

Step-by-step explanation:

$(2 \sqrt{2} \cos(45) \times \cos(60)) +( 2 \sqrt{3} \sin(30) \times \tan(60) ) - \cos(0) = (2 \sqrt{2 } \times \frac{1}{ \sqrt{2} } \times \frac{1}{2} ) + (2 \sqrt{3} \times \frac{1}{2} \times \sqrt{3} ) - 1 = 1 + 1 - 1 = 1$

Answer 2

Answer :

3

Solution :

→ 2√2 cos 45° × Cos 60° + 2√3 Sin 30° × tan 60° - Cos 0°

→ 2√2(1/√2) × 1/2 + 2√3(1/2) × √3 - 1

→ 2 × 1/2 + √3 × √3 - 1

→ 1 + 3 - 1

→ 3
