Answer:x = 30°Explanation:If line m is parallel to line n (m || n), then we know that the 54° angle and (x+24)° angle are corresponding angles. If these angles are corresponding, it means that they are equal to one another due to their location being the same on each lines m and n. If this is true, then so is the following:54° = x° + 24°Solve for x:x° = 54° - 24° = 30°
