last one for the rest of my life lol jk but im done til like forever please answer someone <3

|dw:1362035703956:dw| First you need to calculate the angle "y" in the diagram

|dw:1362035900270:dw| You minus 10 from 90 degrees, because its right angle, y=90-10=80 degrees

6. .Sam.

Then from $\sin(y)=\frac{Opposite}{Hypotenuse} \\ \\ \cos(y)=\frac{Adjacent}{Hypotenuse} \\ \\ \tan(y)=\frac{Opposite}{Adjacent}$ You use cos(y) because its the want we needed and have numbers to solve, $\cos(y)=\frac{Adjacent}{Hypotenuse} \\ \\ \cos(80)=\frac{500}{x} \\ \\ x=\frac{500}{\cos(80)} \\ \\x=2879.38m$
