Answer:
134.3
Step-by-step explanation:
In
a right triangle, look at sides XW and XZ.
![\frac{XW}{XZ}=\frac{\text{adjacent}}{\text{hypotenuse}}=\cos{82^\circ}\\\\XW=(XZ)\cos{82^\circ}](https://tex.z-dn.net/?f=%5Cfrac%7BXW%7D%7BXZ%7D%3D%5Cfrac%7B%5Ctext%7Badjacent%7D%7D%7B%5Ctext%7Bhypotenuse%7D%7D%3D%5Ccos%7B82%5E%5Ccirc%7D%5C%5C%5C%5CXW%3D%28XZ%29%5Ccos%7B82%5E%5Ccirc%7D)
You now need to find XW.
In
the measure of angle XZY (the one at the top) is 180 - (82 + 67) = 31 degrees.
Using the Law of Sines in triangle XYZ,
![\frac{XZ}{\sin{67^\circ}}=\frac{540}{\sin{31^\circ}}\\\\XZ=\frac{540 \sin{67^\circ}}{\sin{31^\circ}}](https://tex.z-dn.net/?f=%5Cfrac%7BXZ%7D%7B%5Csin%7B67%5E%5Ccirc%7D%7D%3D%5Cfrac%7B540%7D%7B%5Csin%7B31%5E%5Ccirc%7D%7D%5C%5C%5C%5CXZ%3D%5Cfrac%7B540%20%5Csin%7B67%5E%5Ccirc%7D%7D%7B%5Csin%7B31%5E%5Ccirc%7D%7D)
Put that into the equation for XW above...
![XW=\frac{540\sin{67^\circ}\cos{82^\circ}}{\sin{31^\circ}}](https://tex.z-dn.net/?f=XW%3D%5Cfrac%7B540%5Csin%7B67%5E%5Ccirc%7D%5Ccos%7B82%5E%5Ccirc%7D%7D%7B%5Csin%7B31%5E%5Ccirc%7D%7D)
A calculator shows that this is approximately 134.3
