Question

me ajudem,pelo amor de Jesus Cristo!!!!!!!!!!!!!!!!​

Answer 1

Resposta:

$\frac{25}{x - 5} = \frac{x + 30}{x + 10} \\ (x - 5)(x + 30) = 25(x + 10) \\ {x}^{2} + 30x - 5x - 150 = 25x + 250 \\ {x}^{2} + 25x - 25x - 150 - 250 = 0 \\ {x}^{2} - 400 = 0 \\ {x}^{2} = 400 \\ x = \sqrt{400} \\ x = 20$

lado AB=25+(20-5)=25+15=40

lado AC=20+30+20+10=80
