Answer:

Step-by-step explanation:
1. Well, when it comes to triangles. Mainly Pythagorean Triple, right triangles whose sides are 3,4,5 or 5,11,12
2. Keeping in mind this a Pythagorean Triple, then x=5
3. Then we can write it as Compound Inequality by combining the Statements for an Inequality of Triangle:
We can write it as

Or we can do:

and:

4. Writing in terms of x:

Answer: no
Step-by-step explanation:
Answer:
83
Step-by-step explanation:
The sum of the angles of a triangle is 180
x + 2x+1 + x+ 15 = 180
Combine like terms
4x+16 = 180
Subtract 16 from each side
4x+16-16 = 180-16
4x = 164
Divide by 4
4x/4 = 164/4
x = 41
The angles are
x=41
x+15 = 41+15 = 56
2x+1 = 2*41+1 = 82+1 = 83
The largest angle is 83
