Question

Ms. Ziolkowski asks her class to write the correct trigonometric function for the triangle shown below.

Answer 1

Answer:

Both are correct

Step-by-step explanation:

They just chose different reference angles to find the ratio.

Rihanna chose angle A:

tan A = opposite/adjacent

tan A = 3/4

Christopher chose angle C:

tan C = opposite/adjacent

tan C = 4/3

Answer 2

Alright so these ratios have many different forms but the way I use to remember the trigonometric ratios is:

SOH

CAH

TOA

This means:

Sine --> Opposite/Hypotenuse

Cosine --> Adjacent/Hypotenuse

Tangent --> Oppositie/Adjacent

With that in mind, number 1:

Would be Sine, or C.

Number 2 would be, Cosine, or E.

And number 3 would be Tangent, or B.

Hope that was helpful.
