Answer:
34.64 ft
Step-by-step explanation:
Distance from the building = 20 ft
Angle of inclination = π/3 radians
The tangent of the angle of inclination must equal the height of the building divided by the distance of the observer from the building:

The building is 34.64 ft tall
Answer:
346 2/3 yards
Step-by-step explanation:
A football field is 100 yards long with each end zone being 10 years long, meaning the total length is 120 yards.
The width is 53 1/3 yards.
The perimeter is all the sides added, and a rectangle's, the shape of the field's, formula is p = 2l + 2w.
So if we plug it in and add it all up:
120 + 120 + 53 1/3 + 53 1/3
Perimeter = 346 2/3
Answer:
Put the green dot at the coordinates (-3, -4). Find -3 on the x-axis and go 4 down.
Step-by-step explanation:
Just move the blue dot five to the left, then five to the left again.
(-3, 1.5)....simply add the x coordinates together, divide them by two, and then do the same for the y coordinates.
