Answer:
w = 519.62
z = 480.38
Step-by-step explanation:
to find w you have to use tan (60)
[tex]\tan 60 = \frac{900}{w}\\\\\sqrt{3}=\frac{900}{w}\\\\w=\frac{900}{\sqrt{3}}\\\\w\approx 519.62[/tex]
and for z
[tex]\tan 42 = \frac{900}{z+w}\\\\0.9 = \frac{900}{519.62+z}\\\\900 = 0.9(519.62+z)\\\\900 = 467.66+0.9z\\\\432.34= 0.9z\\\\z \approx 480.38[/tex]
