Need to get this done but was sick and nobody can give me notes on how to solve. can someone teach me or expkain?

1. sin(x) = 6/10 = 0.6

2. sin(x) = 9/(3sqrt10) = (9sqrt10) / (3sqrt10)^2 = 9sqrt10 / 30 = 0.95

3. tan(x) = 3/4 = 0.75

4. cos(x) = 8/10 = 0.8

5. cos(x) = 0.53 (You know x = 45 because this is a 45/45/90 special right triangle)

6. tan(x) = (3sqrt7) / 9 = 0.88

Step-by-step explanation:

Remember the acronym "SOH CAH TOA"

SOH: sine = opposite / hypotenuse

CAH: cosine = adjacent / hypotenuse

TOA: tangent = opposite / adjacent

b

step-by-step explanation:

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.
