Let's start by identify a 30-60-90 triangle
If we compare those two traingles we can stablish the following relation:
![\begin{gathered} a\sqrt[]{3}=6\sqrt[]{3} \\ \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20a%5Csqrt%5B%5D%7B3%7D%3D6%5Csqrt%5B%5D%7B3%7D%20%5C%5C%20%20%5Cend%7Bgathered%7D)
Therefore, a=6
u is the opposite side to the 90° angle, therefore

on the other hand, v is the opposite side to the 30° angles, so
Huh? 5x100 = 500. Is that the question
It would be 20.4 km because if 1cm is 12km then you just have to multiply 1.7 x 12 = 20.4.
Answer: B
Step-by-step explanation:
9.62112750.....
area = πr²
3.5 ÷ 2 = 1.75
1.75² × π = 9.6211250....
= 9.6 ft²
