Answer 1

Răspuns:

a) 54°12'+10°23'=64°35'

b)40°40'+2°10'*2=40°40'+4°20'=45°

c)

$\frac{13 \times 14}{2} - 90 = 13 \times 7 - 90 = 91 - 90 = 1 \: grad$

d)

$\frac{14 \times 15}{2} \times \frac{1}{21} + 85 = 5+ 85 = 90 \: grade$

e)

$1°1'(1+2+3+...+16)=1°1' \times \frac{16 \times 17}{2} = 8°8'*17=138°16'$

f) 180°-(24°24'-24°24')- 40°=180°-40°=140°
