Question

Converter graus para radianos: a) 50° b) 65° c) 90° d) 145° e) 230° f) 240° g) 275° h) 315°

Answer 1

a) 180º = π rad então 50º = x
    180/50 = π rad/x
x = 5π rad/18

b) 180/65 = π rad/x
     x = 13π rad/36

c) 180/90 = π rad/x
     x = π rad/2

d) 180/145 = π rad/x
    x = 29π rad/36

e) 180/230 = π rad/x
     x = 23π rad/18

f) 180/240 = π rad/x
    x = 4π rad/3

g) 180/275 = π rad/x
     x = 55π rad/36

h) 180/315 = π rad/x
     x = 65π rad/36
