Question

Someone please help! find x round to the nearest tenth! trigonometry!​

Answer 1

x = 745.5 ft

Explanation:

Look at the picture.

Use sine:

`sine=(opposite)/(hypotenuse)`

We have a measure of the angle and length of the opposite:

`\alpha=28^o,\ opposite=350\ ft`

`\sin28^o\approx0.4695`

Substitute:

`(350)/(x)=0.4695`

`(350)/(x)=(4695)/(10000)` cross multiply

`4695x=3500000` divide both sides by 4695

`x=(3500000)/(4695)\to x\approx745.5`
