Easy, first you must assign a variable to the angle you are finding, x.
Then, if the angle is on a straight line then the total will be 180.

You should have one angle measument given, such as
An angle with x degrees and one with 72 lie on a straight line.
Then, all it is is x+72=180 which can be rewritten as 180-72=x so x must equal 108!
Same goes for to angles in a right angle, but replacing the 180 with 90.
Now if you are finding a missing angle measure in triangles all you do is add the given measures and subtract from 180 to get the missing measur, x.
Language of Algebra
The whole point of using n in algebra is that it stands for an unspecified number. Until you have an equation (or inequality) that involves n and solve it for a value of n.
When given two names (variable expressions) for the same quantity, you can use algebra to solve the equation.

A protractor is used for measuring angles and the 3 angles in a triangle add up to 180 degrees.

No, you do not need to know all the side lengths and angle measures to solve a triangle. You can solve a triangle using various methods, such as the Law of Sines or the Law of Cosines, if you have sufficient information, like two angles and one side (AAS or ASA), or two sides and the included angle (SAS). Additionally, having all three side lengths (SSS) is also enough to determine the triangle's angles.
By using trigonometry or using Pythagoras' theorem for a right angle triangle.
Solve for variables using equations graphs and tables. There is also a lot of substituting
Algebra is using variables such as x to solve a problem. One example is x+3=8 in which x equals 5.
A projectile has vectors. This can be put in x and y. If it's simple physics, there is really not much algebra.
