It might be c. im not really sure, but that's what I got. sorry if its wrong...
The answer is A
-6.9+6.8 is equal to -0.1, and -5.4+5.5 is 0.1. If you add those two together, you get zero.
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!
Answer:
