Which of the following statements are true for any triangle? Choose all that apply. (Hint: Create a right triangle and make up three side lengths. Use ratios made from this triangle to complete the problem below).

a. tan x = sin x / cos x

b. tan x = cos x / sin x'=

c. sin x = cos x * tan x

d. cos x = sin x * tan x

e. cos x = sin x / tan x

a. tan x = sin x / cos x is true for any triangle.

b. tan x = cos x / sin x is not true for any triangle as it would only be true for a triangle with a 90-degree angle.

c. sin x = cos x * tan x is not true for any triangle as it would only be true for a triangle with a 45-degree angle.

d. cos x = sin x * tan x is not true for any triangle as it would only be true for a triangle with a 45-degree angle.

e. cos x = sin x / tan x is not true for any triangle as it would only be true for a triangle with a 45-degree angle.
