Question

Find y..........................................................................................................................................

Answer 1

$sin30 = \frac{o}{h} \\ sin30 = \frac{5}{x} \\ x = \frac{5}{0.5} \\ x = 10$

${10}^{2} + {10}^{2} = {y}^{2} \\ 100 + 100 = {y}^{2} \\ 200 = {y}^{2} \\ \sqrt{200} = y \\ 14.14 = y$
