Question

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

Answer 1

supplementary angles sum up to 180 degrees

Let the angle be x
and other angle (x-6)

x+(x-6)=180
2x=172
x=86

Hope I made it simple

Answer 2

let angle =A,
then it's supplement angle=180-A,

A+6=2(180-A),

A+6=360-2A,

3A=360-6,

3A=354,

A=118,

then
supplementry angle=180-118=62°
