It is a right angle triangle
complementary angles add to 90 degrees subtract from 90 90-35 = 55
A pair of complementary angles sum up to 90 degrees. In this instance, the complement of a 55-degree angle is 90 - 55 = 35 degrees.
Be nice on here its 55
90 (of course) and 55
Because they add up to 90 degrees
The definition of complementary angles are ones that add up to 90 degrees.
90 - 55 = 35
55+35 = 90
A pair of angles are complementary if their sum is 90 degrees. Therefore, the complement to a 35 degree angle measures 90 - 35 = 55 degrees. This can be effectively displayed when placing both angles so that they form a right angle.
The sum of the angles of ANY n-sided polygon is (2n - 4) right angles. In your example n = 35 so (70 - 4) x 90 ie 5940 degrees
Only if the polygon is a regular quadrilateral.
If all of its exterior angles are 90 degrees then it will have 4 sides
