Answer 1

Do you know trigionometry?

Answer 3

use the ratios of a 30 60 90 triangle :)

Answer 4

30 60 90
1 sqrt(3) 2
those are the ratios

Answer 5

30 60 90
1 sqrt(3) 2

as you can see we are given the measurement for 90 which is 10.

from the table it says 90's side is twice as big as 30's or in other words 30's is half as big.

30's side is 5

now we just set up an equation

since 90 is 2 times bigger than 30 that can be expressed as

30's_side *2=90s_side

we can now safely assume that 60s side expression will look similar

30s_side*sqrt(3)=60s_side

now we plug in
5*sqrt(3)=8.66


that simple.

Answer 6

5,8.66,10
