Given that cos(30°) = cos(45°)cos(15°) + sin(45°)sin(15°), it follows that cos(30°) =

mario62 [17]

Answer:

$cos(30\°) = cos(45\°-15\°)$

Step-by-step explanation:

To solve this problem you must know the formula of subtraction of angles for the function cosx.

The formula is:

$cos(h-d) = cos(h)cos(d) + sin(h)sin(d)$

We can write 30° as: 45° - 15°

Then:

$cos(30\°) = cos(45\°-15\°)$

Using the formula for subtraction of angles we have:

$cos(45\°-15\°) = cos(45\°)cos(15\°) + sin(45\°)sin(15\°)$

Notice that we have achieved the expression shown in the statement

Finally:

$cos(30\°) = cos(45\°-15\°)$

The figure shows Polygon ABCD and some of its transformed images on a coordinate grid:

Black_prince [1.1K]

Based on the fact that the Polygon ABCD was translated, then the polygon that is a translation of it will be Polygon 3.

<h3>What polygon is the translation of Polygon ABCD?</h3>

When a shape is translated, it is taken as it is from one area of the coordinate plane, to another area of the plane.

This means that it doesn't change in height, or orientation.

The only polygon that still looks like Polygon ABCD is Polygon 3 which means that it is the translated version.
