Question

In which triangle is the value of x equal to tan−1?

Answer 1

Answer:

Step-by-step explanation:

By definition, the tangent of an angle is given by:

tan x = \frac{C.O}{C.A}

Where,

C.O: opposite leg

C.A: adjacent leg

x: angle

Therefore, for the last triangle we have:

tan x = \frac{3.1}{5.2}

Clearing the value of the angle:

x = tan^{-1}(\frac{3.1}{5.2})
