HELP ASAP Find the exact value of sin15° by using a sum or difference formula. BRANLIEST

The exact value of sin 15° is .

Solution:

45 – 30 = 15

sin 15° can be written as sin (45° – 30°).

Using trigonometric difference formula:

sin(A – B) = sin A cos B – cos A sin B

sin (45° – 30°) = sin 45° cos 30° – cos 45° sin 30°

The value of sin 45° =

The value of cos 30° =

The value of cos 45° =

The value of sin 30° =

Substitute these values, we get  

Hence the exact value of sin 15° is .

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.

the answer is 150.6

step-by-step explanation:

you multiply .02 by 30 and get .6.

and then you multiply 5.00 by 30 and get 150.

hope this !
