Question

Na figura, calcular os valores de x e y.

Answer 1

Hipotenusa²=Cateto²+Cateto²

Hipotenusa (D,O) = X; Cateto (D,A) = 16; Cateto (A,O) = 12. Portanto:

X²= 16²+12² => X²=256+144 => X²=400 => X=√400 => X= 20

Hipotenusa (D,C) = Y; Cateto (D,O) = 20; Cateto (O,C) = 15. Portanto:

Y²=20²+15² => Y²=400+225 => Y²=625 => Y=√625 => Y= 25
