the angels of atriangle are in A.P. , the greast is five times the least , find their angels in degrees .
I know math is heavenly, but triangles have angels ??
If the smallest angle is x, then the largest is 5x
If they are in AP, then the middle angle must be 3x
(note: 3x - x = 5x - 3x , using the common difference relationship)
then x + 3x + 5x = 180
9x = 180
x = 20
the angles are 20°, 60° , and 100°
