The port support for a window
air conditioning unit forms a triangle and an exterior angle. The sides are (
5x - 6) degreesand the other angle is 3x degrees and last angle is 90 degrees.
The su, of the interior
angles of the triangle is 180
( 5x - 6) + 3x + 90 = 180
X= 12, so the angles are 54
and 36
The exterior angle will also
form a 180 degree with the interior
Depending which exterior
angle
1. ) 180 – 54 = 126
2.) 180 – 36 = 144
