Question

Given cos x = 12/13 and sin x = 5/13
What is ratio for tan x?

Answer 1

• cos x = 12/13
• sin x = 5/13

we know that

• tanx = sin x /cosx

so

`\rm \pink{ \tan(x) = ( \sin(x) )/( \cos(x) ) } \\ \\ \tan(x) = \large{\frac{\frac{5}{ \cancel{13}} }{ \frac{12}{ \cancel{13}}}} \\ \\ \tan(x) = (5)/(12)`
