Answer 1

Please look at the images I have attached.

Hopefully they should teach you how to work out the answer in a clear way, so that you know how to answer these questions in the future!

Please ask if you need me to explain anything further!

Answer 2

x = 80.4

Explanation:

Use tangent

`tangent=(opposite)/(adjacent)`

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

`\alpha=15^o,\ adjacent=300`

`\tan15^o\approx0.2679`

Therefore we have the equation:

`(x)/(300)=0.2679` multiply both sides by 300

`x=80.37\to x\approx80.4`
