$<b>Sin a=Sinb<b>$

$<b>Cancel sin on both Sides because it's similar.<b>$


then..

$\bold{ \huge{ \color{tomato} \frac{sin \: a}{sin \: b} = 1}}$

$\bold{ \huge{ \color{gold} \frac{a}{b } = 1}}$

$\bold{ \huge{ \color{tomato} {cross \: multiplication}}}$


$\bold{ \huge{ \color{tomato}{a = b}}}$


$\bold{ \huge{ \color{green}{its \: proved}}}$
