# Math Help - finding the angles to the nearest degree

1. ## finding the angles to the nearest degree

Find the tangents of the angles of the triangle ABC. Also FInd the angles to the nearest degree. (This must be expressed in minutes degrees and seconds. And there are no negative angles)
A(-3,1), B(3,5), C(-1,6)

Hi Im using the formula
$tan\theta = \frac{m_2 - m_1}{1+ (m_2)(m_1)}$

very much appreciated
Merry xmas!

2. ok is this correct?
$A = 34^\circ 30' 30.68''$
$B = 47^\circ 43' 34.72''$
$C = 97^\circ 45' 5.46''$
but when i sum this up the result would be a 179 degrees more

$A \:= \:34^o\,30'\,30.68''$
$B \:= \:47^o\,43'\,34.72''$
$C \:= \:97^o\,45'\,\boxed{5.46''}$ ← here!
$C \:=\:97^o\,45'\,54.60''$
