Answer:
144
Explanation:
The angles on the line next to the big c must add up to 180, and 180-58=122, so the space next to the 58 must be 122
The interior angles of a polygon can be calculated with 180(n-2) where n is the sides, so a pentagon has 540 degrees of interior angles
540 - 96 - 88 - 90 - 122 = 144
