Question

Express the following angle in degree , minutes and second 78.87°​

Answer 1

Answer:

i) 74.87°

since it is known that

1°= 60 '(minutes)

1'= 60''(seconds)

therefore this expression can be written as

74°(0.87×60) '

74°(52.2)'

or

74°52'(0.2×60°)

74°52'12"

ii) -30.6940

-30°(0.6940×60)'

-30°(41.64)'

-30°41'(0.64×60)"

-30°41'38"

these are the answers for the que you asked
