Question

Qual o valor de X na figura?
A) 2,2
B) 16,2
C) 18,2
D) 4,2
E) 1,8

Answer 1

tan(60°)=AC/6  

AC=6 * tan(60°)

AC= 6 * (√3)

tan(45°)= AC/(x+6)

1 = AC/(x+6)

x+6= AC

x+6=6√3

x= 6√3-6

x = 4,39230

Answer 2

Resposta:

tan(60°)=AC/6

tan(60°)=AC/6AC=6* tan(60°)

tan(60°)=AC/6AC=6* tan(60°)AC= 6* (√3)

tan(60°)=AC/6AC=6* tan(60°)AC= 6* (√3)1

tan(60°)=AC/6AC=6* tan(60°)AC= 6* (√3)15.0

tan(60°)=AC/6AC=6* tan(60°)AC= 6* (√3)15.0tan(45°)= AC/(x+6)

tan(60°)=AC/6AC=6* tan(60°)AC= 6* (√3)15.0tan(45°)= AC/(x+6)1= AC/(x+6)

tan(60°)=AC/6AC=6* tan(60°)AC= 6* (√3)15.0tan(45°)= AC/(x+6)1= AC/(x+6)x+6= AC

tan(60°)=AC/6AC=6* tan(60°)AC= 6* (√3)15.0tan(45°)= AC/(x+6)1= AC/(x+6)x+6= ACx+6=6√3
