Answer:
x = 80.4
Step-by-step explanation:
Use tangent
[tex]tangent=\dfrac{opposite}{adjacent}[/tex]
We have a measure of the angle and length of the adjacent:
[tex]\alpha=15^o,\ adjacent=300[/tex]
[tex]\tan15^o\approx0.2679[/tex]
Therefore we have the equation:
[tex]\dfrac{x}{300}=0.2679[/tex] multiply both sides by 300
[tex]x=80.37\to x\approx80.4[/tex]
