angle C + angle B = 2 angle A, Find angle A |
|
Answer» Let the nagel A x to be x.X+angle c +angle b = 180X+2(x)=180 as because angle c +angle b=2angle a 3x=180X=180/3X=60So, angle a =60 angle C + angle B= 2angle AC+B+A=2 angle A+ A. (adding angle a to both side) We know that A+B+C=180 degreeHence, 2 angleA+A=1803 angle A=180angle A=180/3angle A= 60 degree. |
