Bonjour,

a) Sin(SLO) = SO/ SL

Sin(SLO) = SO / 5.5

Sin(SLO) /1 = SO / 5.5

SO = 5.5 × sin(27)

SO = 2,50 cm

b) tan(SOL) = SL/SO

tan(SOL) = 7/SO

tan(SOL) /1 = 7/SO

SO = 7/ tan(56)

SO = 4.72 cm

c) sin( LOS) = LS/SO

sin( LOS) = 5/ SO

sin( LOS)/1 = 5/SO

SO = 5 / sin(73)

SO= 5,23 cm

Voilà, Bonne soirée
