What are the three main functions in trigonometry? The __________________ is opposite the right angle. The __________________ side is opposite the (reference) angle. The __________________ side is next to the (reference) angle. Which two sides are interchangeable, depending on the reference angle? How does the phrase, SOHCAHTOA, help us remember the trig ratios?

Respuesta :

Answer:

Please check explanation for answers

Step-by-step explanation:

1. the three main functions of trigonometry are;

The sine

The cosine

The tangent

2. The hypotenuse is opposite the right angle. The opposite side is opposite the reference angle. The adjacent side is next to the reference angle

3. The opposite and adjacent are the sides which are interchangeable depending on the reference angle.

4. SOHCAHTOA

SOH means ;

Sine = opposite/hypotenuse

CAH;

cosine = Adjacent/Hypotenuse

TOA;

Tangent = opposite/adjacent
