Yes, every right triangle has two complementary angles.
This is because you know that the interior angles of a triangle have to add up to 180 degrees.
A right angle is 90 degrees, so the remaining two angles have to add up to (180-90) degrees, or 90 degrees.
Two angles whose sum is 90 degrees are complementary.
first most important effect is the erosion and the second most important effect is weathering.
