Question #665f7

Answer 1

smaller angle `=81^@`
larger angle `=99^@`

Explanation:

Two angles are supplementary when they add up to `180^@`.

Let the smaller angle be `x`,
`=>` larger angle `= x+18`
`=> x+(x+18)=180`
`=> 2x+18=180`
`=> 2x=180-18=162`
`=> x=162/2=81^@`

Hence, smaller angle `= x=81^@`
larger angle `=x+18=81+19=99^@`
