Answer:

<h3>cos 112° cos 45° + sin 112° sin 45° = cos(67)°</h3>

Step-by-step explanation:

Given trigonometric expression

cos 112° cos 45° + sin 112° sin 45°

We know, the trigonometric identity

<em>cos (A-B) = cos A cos B + sin A sin B.</em>

On comparing cos 112° cos 45° + sin 112° sin 45° and cos A cos B + sin A sin B, we can see that A= 112° and B = 45°.

Plugging value A= 112° and B = 45° in cos (A-B), we get

cos ( 112- 45) = cos(67)°

<h3>Therefore, cos 112° cos 45° + sin 112° sin 45° = cos(67)°</h3>

Step-by-step explanation:

sqrt(5x)×(sqrt(8x²) - 2×sqrt(x)) =

sqrt(5x × 8x²) - 2×sqrt(5x × x) =

sqrt(40x) × x - 2x × sqrt(5) =

2x×sqrt(10x) - 2x×sqrt(5)

therefore, the last option is correct.
