The eastern roman empire/ Byzantine Empire fell in 1453. hopefully this helps.
Answer:
II think the answer might be 12ft by 11ft i'm not sure
Step-by-step explanation:
2/9×5=10/45
3/5×9=27/45
so 3/5 is bigger then 2/9
5/7×5=25/35
3/5×7=21/35
So 5/7 is larger than 3/5
So from least to greatest the numbers are
2/9 then 3/5 then 5/7
So your answer is A
Answer:
ST = 12 units
Step-by-step explanation:
As RA is parallel to ET, the angle in R is equal to the angle in T, and the angle in A is equal to the angle in E, so the triangle RAS is similar to the triangle SET.
If RT is 21 units, we have that RS + ST = 21 -> RS = 21 - ST
Using a rule of three with the sides of the triangle (as they are proportional), we have:
RS / ST = AR / ET
(21 - ST) / ST = 6 / 8
4 * (21 - ST) = 3*ST
84 - 4*ST = 3*ST
7*ST = 84
ST = 12 units
