In a right triangle, if cos x = 1/2, then what is tan x?
Masteriza [31]

The value of tan x when cos x= 1/2 is; √3

<h3>Right-angled triangles</h3>

From Trigonometric identities of right Triangles;

It follows that;

  • cos x = adj/hyp

Hence, the opposite of angle X is;

  • Opp = √(2²-1²)

  • Opp = √3.

Hence, it follows that tan x;

  • tan x = opp/adj = √3/1

Hence, the value of tan x = √3.
