To find an angle without using a calculator, you will need to use a trig identity. Determine which angle it is and use its corresponding trig identity.
A corresponding angle is related to a primary angle. Subtract the primary angle measure from 180 degrees, to obtain the corresponding angle measure.

If the angle is a lone, random angle, I believe you would need a protractor to determine the precise size of the angle (in "degrees"). However, you could, in this case, roughly guess as to whether the angle is acute, obtuse, or right (if the little rectangle is shown in the angle). Of course, if an angle is in a position where one can determine its measure using known postulates or theorems, finding the size of this angle becomes much easier. For example, if you know the measure of one angle and you must determine the measure of another angle, but these two angles are vertical angles, or are corresponding angles (by the corresponding angles postulate), you can indeed determine the measure of this angle without a protractor. Additionally, another example is that if you knew a pair of angles were either supplementary angles, complementary angles, or a linear pair, and you were given the measure of one of these angles, you could determine the measure of the other angle without a protractor. Therefore, it depends on the angle you're looking at.
To find the measure of an angle, you need to know the size of the entire angle and the other angles within the angle. Then, you subtract the smaller, known angles from the entire, large angle and you should get the measure of the missing angle.
You cannot measure an angle using a ruler.

yes you can still determine the angle measure!

You need to give more information... you're probably going to use a trig identity though.

Pythagorean Theorum. A2+B2=C2 That is the topic of study in trigonometry. Trig gets into the trig functions (sine, cosine, tangent...) and since the subject is quite involved, it can't be adequately explained in this type of setting. However... Imagine a right angle triangle, any right angle triangle (that means a triangle in which one side has 90 degrees but you don't necessarily know any other angle of the triangle. If you want to know a specific angle of the triangle (other than the right angle), you COULD measure two lengths of the triangle and calculate the angle using trig functions. The hypotenuse is the segment of the triangle that is opposite the right angle. To calculate the angle in question, measure the OPPOSITE segment (that means the segment that is furthest from the angle), then measure the hypotenuse (explained above). At that point you divide the length of the opposite segment by the length of the hypotenuse and look up the results in your handy sine table (or use your calculator if it has trig functions) and it will give you the angle. Phew! That was a long explanation, and to go into trig functions any further would require a classroom, but basically that's how you would solve a right triangle question.

The supplementary angle of 53 degrees is 127 degrees
To find the measure of an angle, you need to know the size of the entire angle and the other angles within the angle. Then, you subtract the smaller, known angles from the entire, large angle and you should get the measure of the missing angle.
The answer depends on the shape and what information you do have about it.
The interior angles of a 2-D triangle will always add up to 180 degrees. To determine the measure of the third angle: 180 - (32 + 75) = 73 degrees
