Which of the following statements are true for any triangle? Choose all that apply. (3 correct answers)
. tan x = sin x / cos x
. tan x = cos x / sin x
. sin x = cos x . tan x
. cos x = sin x . tan x
. cos x = sin x / tan x

Respuesta :

tan(x) = sin(x)/cos(x) is one trig identity you should memorize. So one of the answers is choice A. 

-----------------------------------------------------

Multiply both sides by cos(x) to get

cos(x)tan(x) = sin(x)
sin(x) = cos(x)tan(x)

Another answer is choice C

----------------------------------------------------

Then we can divide both sides by tan(x) to get

sin(x)/tan(x) = cos(x)
cos(x) = sin(x)/tan(x)

Choice E is another answer.

----------------------------------------------------

In summary the answers are: A, C, E

Trigonometry is the branch to the mathematics that deals with the study of the relationship between the sides of the triangle (right-angled triangle) or its angles

What I do with trigonometry?

There are three trig ratios you need to know:

  • sine
  • cosine
  • tangent

tan(x) = sin(x)/cos(x) is one trig identity you should memorize. So 1 of the answers is choice A.

Multiply both sides by cos(x) to get

cos(x)tan(x) = sin(x)

sin(x) = cos(x)tan(x)

the Another answer is choice C

Then we can divide both sides by tan(x) to get

sin(x)/tan(x) = cos(x)

cos(x) = sin(x)/tan(x)

Choice E is another answer.
