Use the formula d = 4t to solve the problem. in the formula, d is the
distance an object falls, in feet, and t is the time an object falls, in seconds.
a quarter is dropped from the two of a building and takes 6 seconds to fall to
the ground. what is the height of the building?
o
a. 2116 feet
o
b. 576 feet
o
c. 96 feet
o
d. 24 feet

d=4t is the initial formula

Plug in 6 into t

d=4(6)

Solve for d

d=24 feet

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°
