Answer:

Step-by-step explanation:

cosx=100/564

x=arccos(100/564)

x=79.79 degrees (to the nearest hundredth of a degree)

The angle of elevation from the base of a flag pole to the top of the monument is to be considered as the 79.79 degrees.

Calculation of the angle of elevation;

Since there is 100 feet from the base of the monument.

And, The distance from the base of a flag pole to the top of the monument is 564 feet

Now the angle should be like

cosx = 100/564

x = arc cos(100/564)

x=79.79 degrees

hence, The angle of elevation from the base of a flag pole to the top of the monument is to be considered as the 79.79 degrees.
