Urgent! need someone to properly calculate for degrees because my calculator doesn't give right answer for some reason!

tan^-1 (2.3/1.4) = # degrees ( is not 1.02)

tan^-1 (17/39.8) = # degrees ( is not .40)

tan^-1 (4.3/15.1) = # degrees ( is not .27)

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
