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.
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
