Answer:
686 becomes 700
Step-by-step explanation:
367+319 = 686
hundreds tens one
6 8 6
We are rounding to the hundreds places
We have to look at the tens place
8>=5 so we will round up
6 becomes 7
686 becomes 700
The area is (BK) times (AK or CK).
If you have no numbers given, it's not possible to find the length of BK, or the actual number that represents the area.
The 30:60:90 proportion is 1:sqrt 3: 2
So,
x = 10/2
x = 5
y = 10/sqrt 3
Finding the area:
1/2 * 5 * 10/sqrt 3
25/sqrt 3
Hope this helps!
