Question

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

Answer 1

x = 10.3

Explanation:

Use sine.

`sine=(opposite)/(hypotenuse)`

We have:

`opposite=x\\hypotenuse=16`

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

Substitute:

`(x)/(16)=0.6428` multiply both sides by 16

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