answer the 5th one​

Answer 1

$\blue{\bold{\underline{\underline{Answer:}}}}$

$\tt: \implies Required \: answer \: is \: \Rightarrow Both \: angles \: are \: {90}^{\circ}$

$\orange{\bold{\underline{\underline{To\:Find:}}}}$

$\tt: \implies Angle \: which \: are \: both \: supplementary \: and \: Vertically \: opposite \: angles$

$\pink{\bold{\underline{\underline{Solution:}}}}$

$\tt: \implies Supplementary \: angles \: are \: those \: angles \: whose \: sum \: is \: {180}^{\circ} \\ \\ \tt: \implies Looking \: at \: options \: we \: can \: see \: that \: sum \: of \: angles \: in \: all \: options \: except \: d \: is \: {180}^{\circ} \\ \\ \tt: \implies Question \: is \: also \: asking \: for \: vertically \: opposite \: angles \: and \: we \: know \: that \: vertically \: opposite \: angles \: are \: equal \: so \: in \: a, b, c\: only \: option \: b \: has \: equal \: angles \: and \: their \: sum \: is \: also \: {180}^{\circ}$

Required answer is

$\green{\bold{\underline{\underline{90^{\circ},90^{\circ}}}}}$
