Internal angles

Find the internal angles of the triangle ABC if the angle at the vertex C is twice the angle at the B and the angle at the vertex B is 4 degrees smaller than the angle at the vertex A.

Result

A =  48
B =  44
C =  88

Solution:


A+B+C=180
C = 2B
B = A-4

A+B+C = 180
2B-C = 0
A-B = 4

A = 48
B = 44
C = 88
