B y C

Answer 1

$Sen30^o = \dfrac{1}{2} \\ \\ \\ \dfrac{1}{2} = \dfrac{x}{10} \\ \\ \\ 2x = 10 \\ \\ \\ x = \dfrac{10}{2} \\ \\ \\ x = 5$

=========

$Cos30^o = \dfrac{ \sqrt{3}}{2} \\ \\ \\ \dfrac{ \sqrt{3}}{2} = \dfrac{y}{10} \\ \\ \\ 2y = 10 \sqrt{3} \\ \\ \\ y = \dfrac{10 \sqrt{3}}{2} \\ \\ \\ y = 5 \sqrt{3}$
