Answer:
16. 1385.6 Feet 17. 220 Feet Tall
Step-by-step explanation:
16. Use the tangent function with the given angle to find the other leg.
tan∅=[tex]\frac{opposite}{adjacent}[/tex]
tan[tex]30^o[/tex]=[tex]\frac{800}{x}[/tex]
x(tan[tex]30^o[/tex])=800
x=[tex]\frac{800}{tan30^o}[/tex]
x=1385.6 Feet
17. Again use the tangent function with the given angle.
tan[tex]70^o[/tex]=[tex]\frac{x}{80}[/tex]
x=80tan[tex]70^o[/tex]
x=219.798
The building is about 220 feet tall.
