Find the smallest positive angle θ in QI for which tan θ = 1

I believe the correct answer is 45 degrees. The smallest positive angle θ in QI for which tan θ = 1 would be 45 degrees. We obtain it as follows:

tan θ = 1

θ = tan^-1 (1)

θ = 45 degrees

Hope this answers the question. Have a nice day.
