At 6:00 PM, a flagpole that is 35 feet tall casts a shadow that is 50 feet long. At the same time, how long will a person's shad
1 answer:
<u>Answer:</u>
The length of the person’s shadow is 5.7ft
<u>Explanation:</u>
Length of the flagpole =a= 35ft
Length of the shadow of the flagpole= b=50ft
Length of the person=c= 4ft
Suppose the length of the person’s shadow is=d
According to the rules of trigonometry
35d=200
d=
d=5.7ft
Hence, The length of the person’s shadow is 5.7ft.

Oooh, looks fun
ok
erm
we might want to know some properties
if
where a=a, then assume m=n
so
minus 17*2^x both sides
use u subsitution, u=2ˣ
solve
or
ac method
2 times 8=16
what 2 number multiply to get -17 and add to get 16
-16 and -1
2u²-1u-16u+8=0
(2u²-1u)+(-16u+8)=0
u(2u-1)+(-8)(2u-1)=0
(u-8)(2u-1)+0
u-8=0
u=8
2u-1=0
2u=1
u=1/2
now
u=2ˣ
8=2ˣ
3=x
and
-1=x
x=-1 and 3
neat problem
