Answer 2

${ \huge{ \pink{ \underline{ \underline{ \red{ \mathbb{ \bigstar{ \purple{answer}}}}}}}}} \\ \bf \: given \: the \: equality \: of \: sin \: a \: = cos \: a \\ to \: find \: the \: value \: of \: a \: \\ solution = > \\ \sf \: now \: we \: have \: given \: a \: that \: sin \: a \: = cos \: a \\ also \: the \: angle \: a \: is \: acute \: to \: sin \: a \: cos \: a \\ \sf \: we \: can \: write \: it \: as \: sin \: a \: = \: sin(90 - a) \\ \sf \: concealing \: sin \: for \: both \: side \: we \: get \: \\ a = 90 = a \\ a + a = 90 \\ 2a = 90 \\ a = 45 \degree \: \\ \bf \: so \: the \: value \: of \: a \: is \: 45 \degree \:$
