If tan theta is equal to 4/3, how do you determine theta?

Answer 1

Use the inverse tangent:

tan θ = 4/3

tan^-1(tan θ) = tan^-1(4/3)

θ = tan^-1(4/3)

Use the inverse tangent function on your calculator to determine the answer.

Answer 2

Inverse Tangent (tan^-1) of 4/3

So tan^-1(4/3) = 53.13 degrees
