1) x = 18*sin 60° = 18*sqrt(3)/2 = 9*sqrt(3)
2) x = 16/sin 45° = 16/ (1/sqrt(2)) = 16*sqrt(2)
3) x = 4/tg 30° = 4/ (1/sqrt(3)) = 4*sqrt(3)
4) Угол KMN = KNM = (180° - 120°)/2 = 30°
x = 30*sin 30° = 30*1/2 = 15
5) x = 10*sin 30° = 10*1/2 = 5
6) Угол PAT = PTA = 45°
x = 30*sin 45° = 30*sqrt(2)/2 = 15*sqrt(2)
7) x = 9*tg 60° = 9*sqrt(3)
8) Угол CAD = 90° - 30° = 60°
x = 6*tg 60° = 6*sqrt(3)
