This would be equivalent to 8.75 X 10 ^ -8 in scientific notation.
Answer:
71.3°
Step-by-step explanation:
A building 62 feet tall casts a shadow 21 meters long . At what angle is the sun shining on the building?
We solve this question using the Trigonometric function of Tangent
tan x = Opposite/Adjacent
Where
Opposite = 62ft
Adjacent = 21 ft
x = Angle
Hence,
tan x = 62/21
x = arc tan (62/21)
x = 71.288262125°
Approximately = 71.3°
Idk use Socratic but if not cry cuz math sucks
Step-by-step explanation:
3x-12=0
Therefore, 3x= 0-12
Therefore, x= -12/3
Therefore, x= - 4
X=-4

Answer:
12.6 inches
Step-by-step explanation:
-The distance covered in one revolution is equivalent to the circumference oif a tire.
#We calculate the Circumference of A:
![C_a=\pi D\\\\=\pi \times 32\\\\=100.5310\ inches](https://tex.z-dn.net/?f=C_a%3D%5Cpi%20D%5C%5C%5C%5C%3D%5Cpi%20%5Ctimes%2032%5C%5C%5C%5C%3D100.5310%5C%20inches)
#We then calculate the circumference of B:
![C_b=\pi D\\\\=\pi \times 28\\\\=87.9646\ inches](https://tex.z-dn.net/?f=C_b%3D%5Cpi%20D%5C%5C%5C%5C%3D%5Cpi%20%5Ctimes%2028%5C%5C%5C%5C%3D87.9646%5C%20inches)
-A has a larger circumference than B and the difference is :
![\bigtriangleup=C_a-C_b\\\\=100.5310-87.9646\\\\=12.5664\approx12.6\ inches](https://tex.z-dn.net/?f=%5Cbigtriangleup%3DC_a-C_b%5C%5C%5C%5C%3D100.5310-87.9646%5C%5C%5C%5C%3D12.5664%5Capprox12.6%5C%20inches)
Hence, Tire A covers 12.6 inches more than B after one revolution.
