Question

me pueden ayudar
como hallo (x+y)??

Answer 1

$\frac{y}{ \sin(30) } = \frac{x}{ \sin(90) } \\ y = 0.5x \\ {(7 \sqrt{3} )}^{2} + {(0.5x)}^{2} = {x}^{2} \\ 147 + 0.25 {x}^{2} = {x}^{2} \\ 0.75 {x}^{2} = 147 \\ x = \sqrt{ \frac{147}{0.75} } \\ x = 14 \\ y = 0.5(14) \\ y = 7 \\ (14 + 7) {}^{2} = 441$
