Question

9) Efetue as operações entre as medidas de arcos indicadas a seguir : a) 17º32´ + 53º21´ = b) 98º23´ + 63º54´ = c) 37º25´ - 22º54´ = d) 104º53´ - 62º44´ =

Answer 1

a)

 17°32'

+53°21'

  70°53'

$\boxed{\boxed{\mathsf{17^{\circ} 32\´ + 53^{\circ} 21\´}=70^{\circ}53'}}}$

b)

  98°23'

+ 63° 54'

 161° 57'

$\boxed{\boxed{\mathsf{161^{\circ} 57 \:\´}}}$

c)

37°25'

-22° 54'

37°25'=36°85'

 36°85'

- 22°54'

  14°31'

$\boxed{\boxed{\mathsf{14^{\circ} 31\:\´}}}$

d)

104°53'

-62° 44'

 42°  9'

$\boxed{\boxed{\mathsf{42^{\circ}9\:\´}}}$
