2. m∠A≈
3. m∠B≈
(Note: Both #2 and #3's answers are degrees)

What are the correct answers for 1,2, and 3?

Please show all the work on how you got your answers.

Answer 1

Find
`AB` using Pythagorean Theorem,

`AB=√(12^2+9^2)=15`.

`A=\tan^(-1)(12/9)=53.1^(\circ)`.

`B=\tan^(-1)(9/12)=36.9^(\circ)`.

Hope this helps.
