Largest angle of the triangle

What is the largest angle of the triangle if the second angle is 10° greater than twice the first and the third is 30° smaller than the second?

Correct result:

B =  0 °

Solution:


System of equations are non-linear.
The equations have the following integer solutions:
A+B+C=180
B = 10 + 2A
C = B-30


Number of solutions found: 1
A1=38, B1=86, C1=56
