Question

11. One of the angle of a pair of supplementary angles is 2 more than its
supplement find the angles.​

Answer 1

let first angle be A,

then

2nd angle will be (A+2),

now according to the queue, we have

1st angle + 2nd angle=180°,

A + A+2 = 180,

2A+2=180,

2A=178,

A=178/2,

A=89,

therefore

1st angle=89°,

2nd angle=89°+2°=91°
