Question

Determine o valor de X

Answer 1

Vamos calcular com as funcoes trigonometrias :

Tg 30¤ = cateto oposto
...................____________
...................cateto adjacente

Tg 30¤ = 50cm
...................______
.........................X

\/3.......50cm
__ = _____
.3.............X

\/3.X = 50 ( 3 ) cm
\/3.X = 150 cm
X = 150 cm
.......___
........\/3

X = 150 . \/3 cm
.......___.....___
........\/3.......\/3

X = 150 .\/3 cm
........______
...............3

X = 50.\/3 cm

\/3 = 1,73

X = 50 (1,73) cm
X = 86,50 cm
