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:

$cos(30\°) = cos(45\°-15\°)$

Why is -4 + 5 = to 1

Firlakuza [10]

-4+5 equals 1 because on a number line -4 is left of 0, and positive 5 is right of 0. So therefore moving from -4 5 spaces right would put you at (pos) 1.
