Step-by-step explanation:
–6(x + 5) + 3 = –2(x + 4) – 4x
–6x – 30 + 3 = –2x –8 – 4x
–6x –27 = –6x –8
–6x + 6x = –8 + 27
0 = 19

Answer:
0.40 foot
Step-by-step explanation:
In the first case, a 50 - foot building casts a- foot shadow (1-foot). Let the angle of elevation of the sun from the shadow be represented by θ.
Then:
Tan θ = 
Tan θ = 
Tan θ = 50
⇒ θ =
50
= 88.8542
= 
The angle of elevation is approximately
.
For a 20-foot pole,
Tan θ = 
Tan
= 
x = 
= 0.4015
= 0.40 foot
The length of the shadow of the pole is 0.40 foot.
