(the side opposite the angle) divided by (the side adjacent to the angle) = tangent of the angle
(the side opposite the angle) divided by (the hypotenuse of the triangle) = sine of the angle
(the side adjacent to the angle) divided by (the hypotenuse of the triangle) = cosine of the angle
Once you have the sine OR the cosine OR the tangent of the angle, you can get the measurement of the angle on a scientific calculator, or look it up in a table of trig functions in a book.

The study is called trigonometry.
Depending on which sides and angle are known you would use one of the trigonometry functions.
if the two lengths are not touching, carefully move one of them until they are. measure the length between the outside ends of the two lengths. this makes a triangle. An angle can be calculated by using trigonometry functions on two of the lengths of a triangle. these can be simple or rather complex
With trigonometry by using the cosine rule
A triangle with a right angle and different lengths for sides is a right, scalene triangle.
By using trigonometry that is applicable to a right angle triangle.

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.
If it has an hypotenuse then it must be a right angle triangle then by using Pythagoras' theorem its hypotenuse is 2.86 cm rounded and by using trigonometry its smallest angle is 35.02 degrees rounded.

rightangle
A right triangle is a triangle in which one angle is a right angle (that is, a 90-degree angle). The relation between the sides and angles of a right triangle is the basis for trigonometry.
