<u>Funciones Trigonométricas</u>
La identidad principal en trigonometría es:

Si sabemos que A es un ángulo agudo (que mide menos de 90°), su seno y coseno son positivos.
Dado que Sen A = 4/5, calculamos el coseno:

Sustituyendo:




Tomando raíz cuadrada:

La tangente se define como:

Substituyendo:


Answer:
Step-by-step explanation:
Step 1 Answer: Yes, 3
Step 2 Answer: Yes, 5
Step 3 Answer: No
Answer: -3060
68
-45
--------
340
272x <-- the x is in place of a zero
--------
3060
times the negative: -3060
Every point on this line has the same y coordinate, which is -2. There is no "rise" at all so rise = 0 while the "run" is any nonzero value you want. If you made the run be say 2, then
slope = rise/run = 0/2 = 0
The slope is 0
Answer: D) 0
note: all horizontal lines like this have a slope of 0. It doesn't matter what the y intercept is
Answer: 
Step-by-step explanation:
Since we have given that

And we know that θ is in the Fourth Quadrant.
So, Except cosθ and sec θ, all trigonometric ratios will be negative.
As we know the "Trigonometric Identity":

It must be negative due to its presence in Fourth quadrant.
Hence,
