Question

75° para radianos ? 45 ° para radianos ? 2 rad para graus ?

Answer 1

Ola!!!

Resolução!!!

Regra de três simples

Graus —————— Rad
180 ——————— π
75 ———————— x

180/75 = π/x

Multiplicando a cruzada

180 • x = 75 • π

180x = 75π

x = 75π/180 : 3

x = 25π/60 : 5

x = 5π/12

R = 5π/12 Rad

***

Graus —————— Rad
180 ———————- π
45 ———————— x

180/45 = π/x

180 • x = 45 • π

180x = 45π

x = 45π/180 : 3

x = 15π/60 : 3

x = 5π/20 : 5

x = π/4

R = π/4 Rad

*"""

Graus —————— Rad
180 ——————— π
x ———————— 2π

180/x = π/2π

π • x = 180 • 2π

πx = 360π

x = 360π/π

x = 360°

R = 360° Graus
