Question

if an angle is 6 degree less than twice its supplement how much does each angle measure

Answer 1

One is 62degree and other is 118 degree.

Answer 2

let the angle be A,
then
its supplementry angle=(180°-A),

therefore

A+6° = 2(180°-A),

A+6° =360° -2A,

then

A+2A=360°-6°,

3A=354°,

A=354°/3,

A=118°,

hence
supplementry angle=180°-118°,

=62°
