| 1. Let’s denote one part by x.
2. Determine what the first angle is equal to:
2 * x = 2x.
3. Find out what the second angle is equal to:
11 * x = 11x.
4. Find the third corner:
23 * x = 23x.
5. Let’s compose and solve the equation.
2x + 11x + 23x = 180 °;
36x = 180 °;
x = 180 ° / 36;
x = 5.
6. One part is equal to x = 5.
7. What is the obtuse angle?
23 * x = 23 * 5 = 115 °.
Answer: The obtuse angle is 115 °.
