Use the tangent inverse to find the angle.....we have

atan(123/170) ≈ 35.89°.......nore that this could also be an angle in the 3rd quadrant, too, since the tangent is also positive there....so 180° + 35.89° = 215.89°

P.S. - The tangent inverse key could be labeled as "atan" or "tan-1 " on your calculator
