Question

the larger of two supplementary angles exceeds the smaller by 18 degrees. find them.

Answer 1

Hey

Here is your answer,

let the angle be x
other angle (it's supplement) =( 180-x)
x+18= (180-x)
2x = 162
x = 162/2 = 81
other angle(its supplement) = 180- x => 180-81 => 99

hope this helps

Answer 2

supplementary angles means sum of those angles is 180.
one angle be x and the other as y.
x + y =180.
let y be larger than x.
y - x =18.
add these equations.
u get 2y = 198. y= 99.
so x= 81..
81,99 are the angles
