Answer:
![\tan \frac{opposite}{adjacent}](https://tex.z-dn.net/?f=%20%5Ctan%20%5Cfrac%7Bopposite%7D%7Badjacent%7D%20)
21.4
Step-by-step explanation:
tan47° = x/20
1.072=x/20
20×1.072= x/20×20
x =20 ×1.072
x= 21.447
x=21.4

Answer:
the answer is 11
Step-by-step explanation:
Due to the was its set up changes the way it looks. 5+(3+x)=19 and once its simplified 8+x=19 just subtract 8 from 19 and you get 11 so x=11.
Answer:
C) 500.83
Step-by-step explanation:
Surface area for a cylinder formula:
SA = 2πrh + 2πr²
Given:
d = 11
r = d/2 = 11/2 = 5.5
h = 9
Work:
SA = 2πrh + 2πr²
SA = 2(3.14)(5.5)(9) + 2(3.14)(5.5)²
SA = 310.86 + 2(3.14)(30.25)
SA = 310.86 + 189.97
SA = 500.83
