Question

no triângulo, determine os valores de x e y: ​

Answer 1

Resposta:

$180 - 117 = y \\ 63 = y \\ \\ 63 + x + \frac{x}{2} = 180 \\ \\ x + \frac{x}{2} = 180 - 63 \\ \\ \frac{x}{1} + \frac{x}{2} = 117 \\\\ \frac{2x + x}{2} = \frac{3x}{2} = \frac{117}{1} \\\\ 3x = 234 \\ x = \frac{234}{3} = 78 <<-----$

63 e 78
