You measure it very, very carefully!
A right angle measures 90 degrees. To find its reflex angle, you subtract the right angle from 360 degrees. Therefore, the reflex angle is 360 degrees - 90 degrees, which equals 270 degrees.
Subtract the angle from 90 degrees and you have the complement Subtract the angle from 180 degrees and you have the supplement
the angle on a straight line is 180 degrees, the angle of semicircle at centre is 180 degrees
To find the complementary angle of 16.5 degrees, subtract 16.5 from 90 degrees. So, 90 - 16.5 equals 73.5 degrees. Therefore, the complementary angle is 73.5 degrees.
To find a complementary angle, subtract the given angle from 90 degrees, since two angles are complementary if their sum equals 90 degrees. For example, if you have an angle of 30 degrees, its complementary angle would be 90 - 30 = 60 degrees. This method applies to any angle less than 90 degrees.
A right angle measures 90 degrees. To find its reflex angle, you subtract the right angle from 360 degrees. Therefore, the reflex angle is 360 degrees - 90 degrees, which equals 270 degrees.

The measurement of angle ABD is 73 degrees. You find this angle by subtracting angle DBC from angle ABC, or 89-16 is equal to 73 degrees.
82 degrees (180 degrees in a triangle)
the supplement of an 82 degrees angle would be 98 degrees. To find the supplement of an angle, take the degrees of the angle you were given and subtract it from 180.

A straight angle measures 180 degrees. To find the degrees of a part of a straight angle, you can use a protractor to measure the angle or use mathematical calculations if you know the relationships between the angles involved. For example, if you have two angles that together form a straight angle, you can subtract one angle from 180 degrees to find the other angle.

To find the reference angle for negative 200 degrees, first convert it to a positive angle by adding 360 degrees, resulting in 160 degrees. The reference angle is then found by subtracting this angle from 180 degrees, yielding a reference angle of 20 degrees. Thus, the reference angle for negative 200 degrees is 20 degrees.
The reference angle for an angle in standard position is the acute angle it makes with the x-axis. For an angle of 288 degrees, first subtract 360 degrees to find its equivalent angle within one full rotation, which remains 288 degrees since it's less than 360. To find the reference angle, subtract 288 degrees from 360 degrees: 360 - 288 = 72 degrees. Thus, the reference angle for 288 degrees is 72 degrees.
