Question

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

Answer 1

Answer:

x = 10.3

Step-by-step explanation:

Use sine.

$sine=\dfrac{opposite}{hypotenuse}$

We have:

$opposite=x\\hypotenuse=16$

$\sin40^o\approx0.6428$        look at the table in the picture

Substitute:

$\dfrac{x}{16}=0.6428$         multiply both sides by 16

$x=10.2848\to x\approx10.3$
