+9 Angle B is 2 times m(angle)A and Angle C is 3 less than 2 times m(Angle)A Find m(Angle) C
Angle B is 2 times m(angle)A and Angle C is 3 less than 2 times m(Angle)A Find m(Angle) C
Angle A=A
AngleB=2A
Angle C=2A - 3
A + 2A + 2A - 3 =180
5A=180 + 3
5A=183
A=183/5=36.6 degrees
B=36.6 x 2=73.2 degrees
C=36.6 x 2 - 3=70.2 degrees
36.6 + 73.2 + 70.2 =180 degrees.
