Question

3. As dimensões de um retângulo são 8 cm e 15 cm. Determine a medida y da
diagonal desse retângulo​

Answer 1

Pelo;

$\boxed{\boxed{\boxed{\mathfrak{Teorema~Pitagoras}}}}$

$\mathsf{y^2=8^2+15^2}\\\mathsf{y^2=64+225}$

$\mathsf{y^2=289}$

$\mathtt{y=\sqrt{289}}$

$\huge\boxed{\boxed{\boxed{\mathsf{y=17~cm}}}}$
