Answer:
x=6.2
Step-by-step explanation:
So to find this we can use the trignometric function sin(Θ):
Perpendicular = x
Hypotonuse = 18
Θ = 20°
sin(Θ) = [tex]\frac{Perpendicular}{Hypotonuse}[/tex]
Substituting our values we get:
Sin(20°) =[tex]\frac{x}{18}[/tex]
Using a calculator we get:
0.34202 = [tex]\frac{x}{18}[/tex]
[tex]x=0.34202*18[/tex]
x=6.15636
So rounding that to the nearest tenth :
x=6.2
