smallest angle is equal to 2 by 18 into 360 degree is equal to 40 degree
let the smallest angle BF then other Angle B 2x
a.t.q.
X + X + 40 =180°
2x=180°-40°
x=140°/2=70°
therefore second largest angle of triangle is equal to 70 degree and the largest in the least 140° and the smallest angle is 40 degree
