Question

transforme em graus:

a) 3.600''
b)240'
c)420'7.200''

Answer 1

Olá.

Vamos seguir essa regra:
$\boxed{\mathsf{1^{\circ}=60'=3.600''}}\\\boxed{\mathsf{1'=60''}}$

$\mathsf{A\ -\ 3.600"}\\\\\mathsf{\dfrac{3.600''}{3.600}=\boxed{1^{\circ}}}\\\\\\\mathsf{B\ -\ 240'}\\\\\mathsf{\dfrac{240'}{60}=\boxed{4^{\circ}}}\\\\\\\mathsf{C\ -\ 420'\ 7.200''}\\\\\mathsf{\dfrac{420'}{60}=7^{\circ}}\ \ \ \ \ \mathsf{\dfrac{7.200''}{3.600}=2^{\circ}}\\\\\mathsf{7^{\circ}+2^{\circ}=\boxed{9^{\circ}}}$

Qualquer dúvida, deixe nos comentários.
Bons estudos.
