Question

find the value of 2 sin 45 degree cos 45 degree​

Answer 1

Answer:

1

Step-by-step explanation:

From the T-ratio Tables,

Sin 45 = 1/ $\sqrt{2}$

Cos 45 = 1/ $\sqrt{2}$

so , 2 sin 45 degree cos 45 ==>

2 *  1/$\sqrt{2}$  * 1/$\sqrt{2}$ ==>

2*1/2 ==>

1

[  1/$\sqrt{2}$   *   1/$\sqrt{2}$   ==>1/2    ]

Answer 2

Answer:

1

Step-by-step explanation:

From the T-ratio Tables,

Sin 45 = 1/  

Cos 45 = 1/  

so , 2 sin 45 degree cos 45 ==>

2 *  1/  * 1/ ==>

2*1/2 ==>

1

[  1/   *   1/   ==>1/2    ]

Answer is Correct
