The sum of two acute angles of a right triangle must equal 90 degrees.
2 angles whose sum is 180 are called supplementery angles.an example of supplementary angles are two right angles.=)
(2n - 4) right angles where n is the number of sides.
Sum of interior angles is (2n-4) right angles There are 66 right angles in 5940 degrees So (2n - 4) = 66 2n = 70 n = 35
The exterior angles sum to 3600 , but the interior angles sum to 23400.
