Triangle adds up to 180 degrees:
Let one side be x
Let middle side be 2x+17
Let the largest side be x+55
Equation:
(x)+(2x+17)+(x+55)=180
4x+72=180
4x=108
x=27

2(27)+17=71
27+55=82.
Hence, the three sides are 27, 71 and 82 degrees.

1. the smallest is x
2. then the mid is 2x+17
3. the largest is x+55
4. the sum of the interior angle in a triangle is 180
so, x+(2x+17)+(x+55)= 180
4x+72=180
4x=180, x=27 then 2x+17(the mid) = 81 and the largest is 82.

(17+2X)+(X+55)+X=180 OR 17+2X+X+55+X=180 OR 4X+72=180 OR 4X=108 OR X=27
PROOF (17+54)+(82)+27=180 OR 180=180
