D)180
E)81

Answer 1

A) 99°

Explanation:

`m \angle \: 4 = 81 \degree...(given) \\ \because \: m \angle \: 8 = m \angle \: 4 \\ (corresponding \: \angle s) \\ \therefore m \angle \: 8 = 81 \degree \\ \\ \because \: m \angle \: 8 + m \angle \: 9= 180 \degree \\ (interior \: \angle s \: on \: the \: same \: side \\ of \: transversal) \\ \therefore \: 81 \degree+ m \angle \: 9= 180 \degree \\ \therefore \: m \angle \: 9= 180 \degree -81 \degree \\ \huge \red{\therefore \: m \angle \: 9= 99\degree} \\`
