In Figure, given that `A B||C D` If `/_2=(3x-10)^@ and /_8=(5x-30)^@,` determine the measures of `/_2` and `/_8`

Text Solution

Verified by Experts

Given that `AB∥CD,/_2=/_8 `(Alternate external angles)
`(3x−10)^@=(5x−30)^@`
`x=10^@`
`/_2=(3x−10)^@`
`=>3xx10−10=20^@`
`/_8=(5x−30)^@`
`=>5×10−30=20^@`
