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.
Supplementary angles: Two angles who measures have a sum of 180. and KMH are complementary because they add up to 180 degrees, which is a straight line. is a straight line. Although not pictured, supplementary angles do not need to be adjacent. Vertical angles: Two angles whose sides are opposite rays. The vertical (opposite) angles are congruent. The example below shows two sets of vertical angles, 1 and 3, 2 and 4.
