Question

Find the value of x, rounded to the nearest tenth.

Answer 1

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) = $\frac{Perpendicular}{Hypotonuse}$

Substituting our values we get:

Sin(20°) =$\frac{x}{18}$

Using a calculator we get:

0.34202 = $\frac{x}{18}$

$x=0.34202*18$

x=6.15636

So rounding that to the nearest tenth :

x=6.2
