Solve for x in the triangle. Round your answer to the nearest tenth.
kramer

Answer:

<h2>x = 10.3</h2>

Step-by-step explanation:

Use sine.

sine=\dfrac{opposite}{hypotenuse}

We have:

opposite=x\\hypotenuse=16

\sin40^o\approx0.6428        <em>look at the table in the picture</em>

Substitute:

\dfrac{x}{16}=0.6428         <em>multiply both sides by 16</em>

x=10.2848\to x\approx10.3
