There is not enough information. Angle A can be anything between 0 and 180 degrees.
If you are talking about a triangle ABC, in which angle C is the right angle then a is the opposite side and b is the adjacent side. tan A = opposite / adjacent
tan A = 490 / 960 = 0.51041666666666666666666666666667
and A = invtan(0.51041666666666666666666666666667) [also called tan-1]
so A = 27.04 degrees
The complement of an angle is equal to 90 degrees minus the measure of the angle. Therefore, the complement of a 72 degree angle would be 90 degrees - 72 degrees, which equals 18 degrees.
a 60-degree angle
It depends on the context - academic qualification, measure of temperature (on which scale), measure of angle, measure of power (of polynomial) and possibly classification of murder/homicide or burns.
The degree measure of five fourths of a right angle is 112.5 degrees

You can measure it. Or you can measure some other quantities (for examples, the lengths of the sides of a triangle), and calculate the angle using trigonometry.
The angle would be 82.4053 degrees, or 82.4 correct to the nearest tenth of a degree.
Two angles are complementary if their sum equals exactly 90 degrees. Two angles are supplementary if their sum equals exactly 180 degrees, so a 30 degree angle is supplementary with a 150 degree angle.
The angle would be .4 if you rounded it to the nearest 10th degree
The complement of an angle is equal to 90 degrees minus the measure of the angle. Therefore, the complement of a 72 degree angle would be 90 degrees - 72 degrees, which equals 18 degrees.
