29° 41' 39" × 8


.....​

Answer 1

60" = 1'

60' = 1°

$8\times(29^\circ\,41'\,39'')~=~8\times29^\circ~+~8\times41'~+~8\times39''\\\\\\8\times(29^\circ\,41'\,39'')~=~232^\circ~+~328'~+~312''\\\\\\8\times(29^\circ\,41'\,39'')~=~232^\circ~+~(5^\circ+28')~+~(5'+12'')\\\\\\8\times(29^\circ\,41'\,39'')~=~232^\circ+5^\circ~+~(28'+5')~+~(12'')\\\\\\8\times(29^\circ\,41'\,39'')~=~237^\circ~+~(33')~+~(12'')\\\\\\\boxed{8\times(29^\circ\,41'\,39'')~=~237^\circ\,33'\,12''}$
