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.
