Here is the word problem:
The second angle of a triangle is 55 degrees more than the first angle. The third angle is 15 degrees less than twice the first angle. Find all three angles.
Here is a demo of me working through the problem.
You might be asking yourself where the four parts are? I was focused on explaining in the demo, but on a test we want to be more careful about our presentation of the solution. Here are the four parts of the answer that I want to make sure are on my paper before I turn it in.

- Part 1: Defining the Variable x is the first angle
- Part 2: Writing the Equation, Inequality, or System of Equations x + x+55 + 2x-15 = 180
- Part 3: Writing the Solution to the Equation, Inequality, or System of Equations x = 35
- Part 4: Write the Answer to Your Question The first angle is 35 degrees, the second angle is 90 degrees, and the third angle is 55 degrees.
