Question

Galera me Ajudem por favor.. é pra amanhã de manhãzinha

Answer 1

Olá!!!

Resolução!!!

Regra de três

a)

Graus ————— Rad
180 ——————— π
x ———————— 3π/4

180/x = π/( 3π/4 )
πx = 180 • 3π/4
πx = 540π/3
πx = 180π
x = 180π/π
x = 180°

3π/4 rad = 180°

b)

Graus —————— Rad
180 ——————— π
x ———————— 5π/6

180/x = π/( 5π/6 )
πx = 180 • 5π/6
πx = 900π/6
πx = 150π
x = 150π/π
x = 150°

5π/6 rad = 150°

c)

Graus ————— Rad
180 —————— π
x ——————— 3π/2

180/x = π/( 3π/2 )
πx = 180 • 3π/2
πx = 540π/2
πx = 270π
x = 270π/π
x =270°

3π/2 rad = 270°
