Add 360, giving the answer as 691 degrees.
Co-terminal angles are angles that share the same terminal side when drawn in standard position, differing only by an integer multiple of 360 degrees (or 2π radians). For example, 30 degrees and 390 degrees are co-terminal because if you add 360 degrees to 30, you arrive at 390. This concept is useful in trigonometry, as it allows for simplification of angle measurements and calculations. In essence, co-terminal angles represent the same direction or position on the unit circle.
Yes.
55 degree
The answer depends on whether the angle is 20 degrees or 20 radians.

Latitude is the measurement of degrees from the equator to the pole so that the pole has a latitude of 90 degrees. Co-latitude is the measurement of degrees from the pole to the equator so that the equator has a latitude of 90 degrees. Also the sum of latitude and co-latitude is always 90 degrees.
No. The angles of a triangle always add up to exactly 180 degrees. A right triangle must have one right angle, i.e. an angle of 90 degrees. That leaves 90 degrees for the other two angles. 38 and 54 add up to 92 degrees, so they can't co-exist with the 90-degree angle in a right triangle.
Two 90 degree angles create a perpendicular angle. A 60 degree angle and 120 degree angle also create a 180 degree sum.
The cosine of 70 degrees is approximately 0.3420. It represents the ratio of the length of the adjacent side to the hypotenuse in a right triangle where one angle measures 70 degrees. This value can be found using a scientific calculator or trigonometric tables.

They are co-terminal angles.
