Answer:
125°
Step-by-step explanation:
The angle marked f° is called an "external angle" of the triangle. Relative to that external angle, the two internal angles marked 44° and 81° are called "remote internal angles." Because f° and the adjacent internal angle are supplementary (add to 180°), and because all of the internal angles of the triangle add to 180°, the measure of f is equal to the sum of the remote interior angles:
f° = 44° + 81°
f° = 125°
5 times 1 + 1 times 1/10 + 5 times 1/100 + 3 times 1/1000
Okay, so it basically means you're subtracting.
I'm going to give some examples of what the answer could be.
1. 5 - 5 = 0
2. 5 - 4 = 1
3. 5 - 3 = 2
4. 5 - 2 = 3
5. 5 - 1 = 4
6. 5 - 0 = 5
Or of course if you feel you would like to switch the order of the problems, go ahead and try that, but no matter what happens, make sure the addition version always equal 5, so just be careful :)
The length of the third side can be expressed as an inequality...
0 < 3rd side < 39, depending on the angle
