Answer:
128.67 feet
Step-by-step explanation:
We would be solving this question using the Trigonometric function of tan.
Tan( of the angle of elevation) = height of the tower ÷ height of the shadow.
Angle of elevation = 65°
Height of the tower = unknown, which is designated as X
Height of the shadow = 60 feet.
Therefore,
tan 65° = X/ 60 feet
We crossmultiply
X = tan 65° × 60 feet
X = 128.67041523 feet.
Approximately, X = 128.67 feet.
Therefore, the tower is 128.67 feet tall.
Answer:
Step-by-step explanation:
4)
28 in base 10
base 5=28*2=56
base 2=28*5=140
5)
7 in base 10
base 5=7*2=14
base 2=7*5=35
6)
100 in base 2
base 5=100*5/2=500/2=250
base 10=100*5=500
7)
10010 in base 2
base 5=10010*5/2=50050/2=25025
base 10=10010*5=50050
8)
10111 in base 2
base 5=10111*5/2=50555/2=25277.5
base 10=100*5=50555
true (I don't know if this is the answer but it would be my guess)
