A triangle has an area of 2035 in², and two of the sides of the triangle have lengths 66 in and 67 in. Find the angle included by these two sides.

Note: There are two possible answers.
Report each answer accurate to 2 decimal places.

acute angle = °
obtuse angle = °

(Remember, the acute angle would be the smaller (<90°) and the obtuse angle would be the larger (>90°).)
