1° × π/180 = 0,01745 rad

a) 26° => 3,14 / 180 x 26° = 0,454 rad

b) 35° => 3,14 / 180 x 35° = 0,611 rad

c) 50° => 3,14 / 180 x 50° = 0,873 rad

d) 64° => 3,14 / 180 x 64° = 1,117 rad

e) 93° => 3,14 / 180 x 93° = 1,623rad

f) 130° => 3,14 / 180 x 130° = 2,268 rad

g) 43° 20'

=> 43° + 20/60°

=> 43° + ⅓° = 43 x 3 + 1 = 129 + 1 = 130°

=> 130° = 3,14 / 180 x 130° = 2,268 rad

h) 52° + 15' = 52° + 15/60°

=> 52° + ¼° = 52 x 4 + 1 = 208° + 1 = 209°

=> 209° = 3,14 / 180 x 209° = 3,647 rad

i) 75° + 30: = 75° + 30/60°

=>75° + ½ = 75 x 2 + 1 = 150 + 1 = 151°

=> 3,14 / 180 x 151° = 2,635 rad

j) 112° + 40' = 112° + 40/60°

=> 112° + 2/3° = 112 x 3 + 2 = 336 + 2 = 338°

=> 3,14 / 180 x 338° = 5,899 rad

k) 12° + 12' + 20"

= 12° + 12/60° + 20/3600°

= 12° + ⅕ + 1/180

= 12 x 180 + 1 x 36 + 1

= 2160° + 36° + 1°

= 2.197°

=> 3,14 / 180 x 2197° = 38,345 rad

l) 46° + 18' + 30"

= 46° + 3/10° + 1/120°

= 46 x 120 + 3 x 12 + 1

= 5.520 + 36 + 1

= 5.557°

=> 3,14 / 180 x 5.557° = 96,988 rad
