Question

Tolong ya caranyaa yg jelas ;w;)

Answer 1

Apanya, ga pake ini itu kok. cuma pake aturan cos sin tan aja.

AB = tan (45/2) x 10

AB = sin (45/2) / cos (45/2) x 10

AB = 1/2 sin 45 : cos'' (45/2) x 10

AB = 2 x 1/2 sin 45 : [cos 45 + 1] x 10

AB = [sin 45 / (cos 45 + 1)] x 10

AB = [V2/2 : (2 + V2)/2] x 10

AB = V2 / (2 + V2) x 10

AB = 1/(1+V2) x 10

AB = (V2 -1)10

AB = 10V2 - 10
