Answer:
- cos(x) = a/c
- sin(x) = b/c
- tan(x) = b/a
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to help you remember the relationships between triangle sides and trig functions. These abbreviations tell you that ...
Sin = Opposite/Hypotenuse ⇒ sin(x) = b/c
Cos = Adjacent/Hypotenuse ⇒ cos(x) = a/c
Tan = Opposite/Adjacent ⇒ tan(x) = b/a

The correct option among all the options that are given in the question is the third option or the penultimate option. I hope it helps you.</span>
Answer:


Step-by-step explanation:
Look at the second equation.
Add 6y to both sides:

Hence,

Substitute this into first equation:
