Question

one of the angles of a triangle is twice the sum of other two angles. find the angle

Answer 1

let common angles be x and x
other angle =2*(x+x) =4x
according to question
4x +x +x =180 ( angle sum property of triangle)
6x =180
x = 180/6 =30
so common angles = x=30°
and other angle = 4x =4 ×30° =120°
