A = C - 13
B = 4C - 11
A + B + C = 180
C - 13 + 4C - 11 + C = 180
6C - 24 = 180
6C = 204
C = 34
A = C - 13 = 21
B = 4C - 11 = 125
Dulce C.
asked 11/13/18In <ABC ,if m<A is 13 less than m<C and m<B is 11 less than four times m<C , find the measure of each angle
A = C - 13
B = 4C - 11
A + B + C = 180
C - 13 + 4C - 11 + C = 180
6C - 24 = 180
6C = 204
C = 34
A = C - 13 = 21
B = 4C - 11 = 125
