An infected first branchial cleft sinus or fistula may cause aural drainage in the absence of otitis media or otitis externa. A child presenting with both a draining ear and a tender mass in the neck may rarely have a first branchial cleft cyst associated with a sinus or fistula tract.
1 What is formed when two complementary angles share one ray? A. the complementary angles form a line with the shared ray B. the complementary angles form a right angle with the shared ray C. the complementary angles form vertical angles with the shared ray D. the complementary angles form an obtuse angle with the shared ray The answer is B right??? Mathematics.
Angle pairs deals with two angles. There are different types of angle pairs. Two angles which has one line in common is called as angle pairs. In angle pairs, the two angles are related to each other.These are complementary angle, supplementary angle, vertical angle, Alternate interior angles, Alternate exterior angles and Corresponding angles.ere, $\angle$ MOP is supplementary angle because, $\angle$ MON + $\angle$ NOP = 180 degrees. Vertical Angles: When two lines intersect each other, angle pairs are formed. In this type of angles, the angles in the opposite direction is said to be vertical angle.
