Step-by-step explanation:
Consider 5 and - 9 to be terms in an arithmetic sequence and we require to find the 6 terms between them.
The n th term of an arithmetic sequence is
= a + (n - 1)d ← d is required
Here a = 5 and = - 9, hence
5 + 7d = - 9 ( subtract 5 from both terms )
7d = - 14 ( divide both sides by 7 )
d = - 2
---------------------------------------------------------
The terms in the sequence are
5, 5 - 2, 5 - 4, 5 - 6, 5 - 8, 5 - 10, 5 - 12, - 9 , that is
5, 3, 1, - 1, - 3, - 5, - 7, -9
With the 6 arithmetic means being
3, 1, - 1, - 3, - 5, - 7

Answer:
- opposite: 4.88
- adjacent: 14.18
Step-by-step explanation:
SOH CAH TOA is a mnemonic intended to remind you of the relevant trig relations.
Sin = Opposite/Hypotenuse ⇒ opposite = 15×sin(19°) ≈ 4.88 units
Cos = Adjacent/Hypotenuse ⇒ adjacent = 15×cos(19°) ≈ 14.18 units
