Question

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

Answer 1

Yes that is correct

Answer 2

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

Explanation:

Remember the acronym "SOH CAH TOA"

SOH: sine = opposite / hypotenuse

CAH: cosine = adjacent / hypotenuse

TOA: tangent = opposite / adjacent
