Johnny is standing on top of a building looking across the river at a taller building. He sights the
angle of elevation to the top of the building to be 4°
and the angle of depression to the bottom of the
building to be 22°. If the buildings are 882 feet
apart, how tall is the other building?

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to

have a nice day!
