Question

How do i find the angle of theta if my right angle triangle has the opposite of 14 and adjacent of 12. i have used theta= tan-1 (14/12)

but the angle i got was not correct

Answer 1

see explanation

Explanation:

What you have written is correct in that

Θ =
`tan^(-1)`(
`(14)/(12)`) = 49.4°

If this is the angle you obtained it is correct.

I suggest you check the mode on your calculator is at deg setting and not rad
